Title: Is boost addictive? discuss.
Post by: SimonC_Here on February 17, 2008, 21:40
Oh my good grief YES!!!

After a long weekend at Marks, I am now the proud owner of a charge cooled turbo'd 2.

Still running at waste gate (~4.7psi) and loving it.
I know I shouldn't have and it wasn't kind to my old and tired clutch, but the new MX5 next to me at the lights thought I wasn't worthy!   s:lol: :lol: s:lol:  
He didn't think so when I pulled over at the speed limit a good 2 car lengths in front (@50mph).

To the guys who fitted it for me, many, many thanks. You all worked really hard for me and managed a Hass + charge cooler in 2 days.
Oh, the cooler was cold when I got home, stone cold, and not a sign of any leaks or drop in coolant level.   s:D :D s:D

To Chris, thanks again for putting up with the horde that descended on you for the weekend, and the food!

Small issue for your minds though.
At about -9.4 psi, if you hold the throttle there it cuts out down to -12psi. A touch on throttle and it's back to normal. I'm going to get it to re learn the idle tomorrow so that might help.

Thanks again to all!

Simon

Congrats Simon
Good to see if was all fixed after the many screw and  thread issues we had yesterday!
oooh and hurry up with those springs, they are rather cool if I say so myself  s;) ;) s;)

she'll take a few days to bed in but follow stus instructions and she should be fine  :-) :-) :-)

for the record thats a chargecooled Hass in 16 hours

previous best was 17 hours for  Hass intercooled which is arguably easier

deduct the time spent on other stuff and we did it in 10 hours flat, bit of a result that.

Si wait until you tastes 10psi you'll wet yourself  :-) :-) :-)

Still fine this morning on the coolant front.
It did throw a cel this morning.
171 (System too Lean (Bank 1) )
and
174 (System too Lean (Bank 2) )

I think it's too lean!  s:) :) s:)

I've disconnected the battery, then forgot you can't actually lock the car with the battery out and my Dev's were frozen in! So nobody look at the green roadster, it's not locked!   s:oops: :oops: s:oops:   s;) ;) s;)

My fuel bill is going to be huge to start off with, I can't stop planting my right foot at any oppertunity. I love the sound of the turbo spooling.

ah yeah the injector cleaner...
A mix of Tesco 99 and what ever the BP ultimate is. 98?

@Liz Jess hasn't been out in it yet as it was dark and cold when I got home and didn't fancy going out, showing off and binning it somewhere  s:oops: :oops: s:oops:

What ever Stu did seems to be holding though.

Have you tried taking air out of the 2 left tyres?
It may not lean as much then   s:P :P s:P
Title:
Post by: aaronjb on February 18, 2008, 11:36
Hmm.. from memory:

System Too Lean is thrown when the long term fuel trim for that bank (or both banks, in this case) exceeds a set threshold - i.e. the ECU is having to add too much fuel in at cruise & idle based on the O2 sensor feedback to maintain a stoichometric A/F ratio of 14.7:1


That might indicate that the eManage map needs a little tweak for your car - perhaps your fuel pressure is a little lower than Marks was, so the eM needs to be pulling less fuel out at idle/cruise.
Title:
Post by: SimonC_Here on February 18, 2008, 12:43
Thanks Aaron,
Just been out at lunch to leave the car to idle for 20 minutes. What the security thought I was doing I don't know!

Anyway, it threw a different CEL. 304 (Cylinder 4 Misfire Detected). I hope it wasn't my soldering...


Simon
Title:
Post by: kanujunkie on February 18, 2008, 13:01
check the soldering asap!
Title:
Post by: aaronjb on February 18, 2008, 13:29
That could also be the one grade colder plugs not really liking extended idling..
Title:
Post by: SimonC_Here on February 18, 2008, 13:34
Quote from: "kanujunkie"check the soldering asap!

Do you know how much electical tape there is around those wires?  s:( :( s:(
Ah well I'll check it whilst the sun is still up.

@Aaron: It had been idling for about 15 minutes before it gave up on me. The revs had just dropped from a very drony 2100 rpm to a very stuttery ~700 rpm.

Erm, possibly silly question, but which one is number 4?


Simon
Title:
Post by: aaronjb on February 18, 2008, 13:39
Number 4 is the one on the left - gearbox end (you always count from crank pulley end)
Title:
Post by: markiii on February 18, 2008, 14:05
there is a specific emanage idle relearn proceedure I'll see if I can find it
Title:
Post by: SimonC_Here on February 18, 2008, 14:33
Typical, if it is no 4 on the left, then it is right under the most difficult place to get.

Can you take off the clip to the injector without taking off the fuel rail?
I don't fancy my chances with my work clothes on in the car park.

I've checked the solders between the original wires and the new ones and they look nice and shiny and firm, don't have a miltimeter here! I seem to remember that the injector in question had to be soldered twice before it was fitted. There was some damage near to the clip where the wire was split. I wonder if the damage was into the clip it's self as well?

So the big question. if I drive home carefully, will it blow up?

Simon
Title:
Post by: markiii on February 18, 2008, 14:35
to remove teh connector from teh injector you need a small flatblade

insert between clip and block and lever it backwards, the clip will pop off
Title:
Post by: SimonC_Here on February 18, 2008, 14:37
Ta, but can it get it home?


Simon
Title:
Post by: markiii on February 18, 2008, 15:08
hang on thinking back to a conversation with Aaron last week

misfire is only the coil reprting that it wasn't able to spark

it's not really a comment on the combustion process persee

check teh connector for teh coilpack and make sure it's properly connected
Title:
Post by: SimonC_Here on February 18, 2008, 15:15
I swapped the coil packs 4 and 3 over whilst trying to work out how to get the clip for the injector out. Didn't make a difference (as long as the left we are all on about is on the passengers side!)

Simon
Title:
Post by: markiii on February 18, 2008, 15:17
it is

tbh as it's not a flashing CEL I'd be tempted to reset and drive it home see if it comes back

Yep, pass side..

Dicky plug maybe?  Though I'm not sure if the ECU feedback control goes as far as the plug, or just the ignitor in the coil..

[edit] And for the record - flashing CEL means "Condition which may cause damage to the CAT due to unburnt fuel" (i.e. prolonged misfire due to no spark on a cylinder).
Title:
Post by: SimonC_Here on February 18, 2008, 15:20
I can't do the plugs here, nothing to take them out with.

It's not flashing.

Simon
Title:
Post by: markiii on February 18, 2008, 15:27
so it's not a prolonged misfire

I'd risk driving it home personally
Title:
Post by: SimonC_Here on February 18, 2008, 15:32
That reader thing you lent me Mark.
Is it:
Car off
Insert reader thing (upside down it seems!)
Key in and turn to "On"
Reader goes:
   It's name scrolling
   - 1 -
   - 2 -
   - 3 -
   Code flashed 4 times
Should it then reset the code?

If yes then the code comes straight back.  s:( :( s:(

Simon
Title:
Post by: kanujunkie on February 18, 2008, 16:32
thats the correct sequence Simon, however if its like mine then it'll do 4 blocks of flashing 3 times before it resets the codes
Title:
Post by: SimonC_Here on February 18, 2008, 16:56
Humm,
After taking off the plastic engine cover, fiddling with the wires and coil packs at lunch time. I didn't put them back for the drive home. I also didn't re attach the oil breather filter.

No engine light and although the idle isn't the most stable thing in the world, it didn't die on me on the way home, including a little detour.

I am wondering if the tension from where we tied up the oil breather pipe worked something loose on the injector clip.
Mark, where can I get a new injector clip/wire that I can replace the dodgy one with? You said it was a different clip to the stock injectors.

Oh and I must remember not to accelerate off that roundabout on the way home. I didn't know you could wheel spin it round a corner in 2nd with a dodgy clutch.  s:evil: :evil: s:evil:

Simon
Title:
Post by: markiii on February 18, 2008, 17:10
that must have been fun

as per what Stu said ref teh odbII reader

I think I have some spare pins let me go look
Title:
Post by: SimonC_Here on February 18, 2008, 17:17
I am almost sure it is that plug that had the one very short wire on it that I had to fix before attaching it to the wiring loom.

Still, grin city, I'm going to take Jess out in it later. I hope she likes it/can live with the extra noise.

Simon
Title:
Post by: Anonymous on February 18, 2008, 19:00
Stuttery idle could just be a minor boost leak post-MAF, which could tie in with the lean codes too?
Title:
Post by: SimonC_Here on February 18, 2008, 20:22
I'll check the hoses tomorrow. It's 2 degrees out there!

Simon
Title:
Post by: markiii on February 18, 2008, 21:00
ok checked and I have spare clips if needed

want me to pop a couple in teh post?
Title:
Post by: SimonC_Here on February 18, 2008, 21:22
If you could please. I'll give the wiring another go this weekend.

Now to decide on the clutch... Organic one from Prolex or the RPS one and get hit by import duty....hummm.


Oh and Mark, can you get Chris to check her bank account please, I've transfered the money.

Simon
Title:
Post by: kanujunkie on February 18, 2008, 21:27
if you have any further problems with those clips then i know where to get them brand new, will cost around a tenner for all 4 + wire and heatshrink. I know i was outvoted on this but if you have any continued problems then let me cut the old clips out rather than leaveing them in where they could short. i can do the wireing properly with the connections further down the loom with the whole thing heatshrunk so that it looks 100% stock and it'll be 100% guranteed no issues ever, up to you.
Title:
Post by: Anonymous on February 18, 2008, 21:31
RPS everytime for me, Si. Lighter than stock feel with more than enough torque capacity? Sounds good to me.

I'm just waiting for this tank to run down and then see if it still happens on the next tank.

Failing that I'll have to get it tuned to my engine, or at least tweeked a little.  s:) :) s:)

Simon
Title:
Post by: aaronjb on February 19, 2008, 13:28
Yep, sounds like the injector sizes may be a little too big in the eManage (making it adjust the fuel too lean to correct for them) - probably a fuel pressure difference down to the age & mileage on the car.

Easy fix with a wideband O2..

I don't think I've got one of those!

Simon
Title:
Post by: aaronjb on February 19, 2008, 14:03
You don't, but I know a man who has one that could be quickly popped in, check the AFR and adjust.. (trickier with the eManage as the stock ECU will constantly try to adjust back to stoic, so you'd have to reset the ECU and do it right after).

[edit] Actually I think you could probably do it without the wideband.. you just need an OBD-II reader than can read the LTFT (Long Term Fuel Trims) out of the stock ECU.. then adjust the injector sizings in the eManage.  A wideband would still be nice to make sure the WOT AFRs don't go lean or too rich, though.
Title:
Post by: spit on February 19, 2008, 18:26
I've had a very similar CEL issue recently, although mine has been a "too rich" syndrome.

I knocked back the Injection ratio by just 2% and its gone, but the ECU is still correcting heavily.

To give you an indication of the flexibility the ECU has at learning and correcting before it hits its limits and throws a CEL, my AFR after a reset was 12.5 at idle, pootling and cruising speeds  s:shock: :shock: s:shock:  . Within a couple of days it had settled back to a healthy 14.7.

Not ideal - I'd rather get round to trimming the emanage map more accurately, but if it aint broke etc ....   s:wink: :wink: s:wink:

Of course, without an AFR you won't know how far over that edge of ECU "trimmability" you are Simon, so best to get Aaron check you over.

Post by: SimonC_Here on February 21, 2008, 09:47
Unless anyone comes up with a good reason not to, I think I'll go with the exedy organic clutch from Prolex.

The RPS is more expensive and I'm likely to get stung by inport duty on top of that. Maybe when the exedy gives up I'll go for the RPS but I doubt the car will still be running by then!

Simon
Title:
Post by: aaronjb on February 21, 2008, 10:00
Stu has the Exedy, right?  In which case (having driven it) it's not a bad clutch at all - took me a few goes to get used to it, but it's not too snappy nor too heavy.

Unlike mine..  s:lol: :lol: s:lol:
Title:
Post by: SimonC_Here on February 21, 2008, 10:20
I think Stu had both from reading the threads.

He didn't like the RPS then he did!

Oh and don't forget the noise on yours as well!  s;) ;) s;)

Simon
Title:
Post by: aaronjb on February 21, 2008, 10:29
No Stu didn't like his RPS at all - and killed it pretty fast, too, from memory.. which is weird.  Dan loved his - so I'm thinking there was something different between the two (I loved the RPS in the Nissan, too, though that's a bit different - vacuum assisted hydraulic clutch  s:) :) s:) )
Title:
Post by: spit on February 21, 2008, 10:36
I'd heard from the Exedy importers in Runcorn that there had been a bad batch of RPS clutches around that time. Fact or fiction I dunno. But Alberto fubarred his fairly quickly too.

Another light clutch worth considering is the ACT.

Exedy is great for the price (from Dave  s:wink: :wink: s:wink:  ). Takes a while to de-judder but it does the job.

Quote from: "spit".... Another light clutch worth considering is the ACT......

I have the ACT and I'm not sure I'd recommend it (mind you I'm only comparing this against stock). When stuck in traffic and the clutch gets hot it doesn't slip at all. Great when you're moving but not fun stuck in London traffic.

being able to return it to stock easily is an excuse, not a reason to leave it in. IMHO the stock connectors should be removed to prevent issues in the future and of course chaffing on any wiring it may be resting on seeing as its a high vibration area. But its your choice

how much?
Title:
Post by: SimonC_Here on February 21, 2008, 14:22
£260 from Prolex which is not a lot more than the GB a couple of years a go and he had one in stock.

RPS street max from PPEEngineering was at £268 (current exchange rate) + whatever the tax man/parcel paper pushers wanted to actually give me it.

RPS from thor-racing was £342.79 + ~50 for bearing +delivery?
It isn't listed for the roadster but I was told that their Matrix 1.8L 1ZZ & 2ZZ* MS-22549-ST would fit.

to give you an idea on miles per clutch,

i got

35K out of the stock one
33k out of the rps
and i'm guessing about the same out of the exedy

so theres not a lot in it on that one, personally i preffer the Exedy out of the 2, it just feels more connected
