TTE and SP didnt fit them.
7psi spring on a small t25xx turbo would suit you.
True, just figured for that price of one, might as well to prevent that back pressure

The demented squirrel is something I wouldn't want to be without.

Probably well worth having with a larger gt28.

Indeed. The Gt28 "worries" me a bit. Knowing what the t2559 is capable of.
Especially combined with the PFC without knock detection.

But, it can all be easily overcome I guess by being a bit more conservative with running boost. Running stock wastegate pressure or perhaps a bit lower.

Besides, they'll use det cans during tuning anyway so as long as nothing changes and it is mapped conservatively, should be perfectly safe without boost controllers etc right?

It should run fine if correctly mapped which is true of anything.
A gt28 won't need to push as many psi to achieve the same power so a 7 psi wastgate spring will be fine.
I personally wouldn't use a PFC unless I already had one sitting around.
For boost some piggyback ECU have better features like boost control. Emanage ultimate springs to mind.
I still want to see someone put an ECUmaster product in a roadster price and features are excellent just a lack of tuners.

Does the ecumaster need specialist tuner skills like the PFC and unichip?

It seems like it has a much more universally understandable interfsce, more like the hondata and emanage solutions

Quote from: "shnazzle"Woody, which Gt28 are you running? And which a/r?

It's the it's a Garrett one from
The MWR kit.

I'm not sure what you mean by a/r.

I do currently plan to use the PFC just because I have one. Is this not a good ECU to use? I don't want to potentially put my car at risk of damaging its self because of a bad choice in ECU.

Sable 06 Reg turbo - staying forever

If I were to add up how much I'd spent on my car, I still wouldn't be able to afford a new Vauxhall Corsa - And I know which one I'd rather have...

No its a smashing bit of kit, it's just a bit old and cumbersome to map and doesn't have some functionality that you'd desire. Plenty cars run it very nicely so I wouldn't worry.

As Scotte said, it lacks boost control for example, which is even built into the emanage ultimate. But then the ultimate is a piggyback so you're always fighting the stock ECU for AFR. Although, there are many ways around it.

The PFC is standalone so it takes much longer to map, as the tuner has to map in open and closed loop. From starting the car to max rpm full throttle and everything in between. A decent Base map will help them and cut down on time so if you can get a pfc map from someone with a near stock configuration, you've saved yourself hundreds

The a/r is a size indicator that really determines the nature of the turbo. Smaller makes for quicker spooling and "fun" but running out of puff quicker. Bigger makes higher top end power but more lag and a bigger wallop.

0.86 would make the top end higher and put you in a good boost position for higher rpm overtakes.
0.64 would make it hit boost quicker and make the car feel very aggressive off the line, arguably more suited to the mr2; think bends. Faster power out of a bend and a lot quicker to respond. Whereas the 0.86 would be more suited to motorway and large track

I believe the PFC already has two maps on it as it was previously used with this turbo kit that I bought. I believe there is a base map and one map running around 220bhp.

I'm not sure how to tell what the a/r is. Is there any way for me to find out.

With the tuning, is there anyone that's been recommmended to map PFC on our cars?

As far as I'm aware, the kit I bought had already been running so my thought was that I could just simply plug it all into my car and it would work.

Just checked the A/R on the turbine housing reads .60

So I'm guessing it will get into boost pretty quickly.

Should all be plug and play then. Drive it gently to the tuner and get it mapped. If it's the same kit, it should only take them a few hours to correct the the map for your setup

0.6 should indeed make for quite a nice drive, in theory.

Stupink is running a Gt28 as well I believe. Or did. He'll know a lot more than me
