Unichip

[jim_jiminy]

Hi, so I think it's time to get a unichip. I have a custom stainless exhaust, sports cat, toyosports decat manifold and was thinking about getting a k & n 57i gen 2 nduction and a unichip.

Anyone got any advice and where to get a unichip from and mapped? I'm in Amersham, Bucks.

Cheers.

Out of curiosity... Why unichip?

[jim_jiminy]

Just saw that most people were happy with them, and price seems reasonable.

What else should I consider?

Cheers.

Have a look at the Ecumaster DET3.

But the unichip, with the injector driver and timing system is indeed one of the most feature-rich piggyback's there is.
It's just finding a mapper for it that's the problem.

If you've found a good mapper that does Unichip, then that's half the problem solved

[jim_jiminy]

Ah thanks! How does the Ecumaster DET3 compare to the unichip? I see it's quite a bit cheaper.

There's redline tuning in Essex that do unichip, fitting and mapping for £480 + vat.

Cheers.

Not a fan of piggybacks have had unichip and DET3 and they do a job for sure but standalone is the way to go.
I don't even think the performance gain is worth the outlay for NA application unless you are doing cams or other engine internals.

I didn't want to burst the bubble but Scotte got in there for me haha.

I agree. I have a bored throttle body, one of the best cone intakes and modified exhaust and can tell you that the piggyback merely smoothed a few things over and added a bit more pull in the top.
It's not worth 480 if you ask me. Not until you get cams.

If that's the plan, wait for the cams. Otherwise you'll have to get it mapped twice.
The Unichip can control VVTI though which is a bonus.

Can the DET3? If so, I'd go DET3.

480 is much better spent on bracing, tyres, brake lines and fresh fluid with some good pads

[jim_jiminy]

Ah I see. Ok well you guys have changed my mind.

I'll spend that on some new bracing and brake lines. My power steering pipes are looking a bit corroded too so that needs attention.

I just want a bit more acceleration   2zz too expensive for me at the mo, turbo looks like a lot of hassle and almost as expensive.

How much hp would new cams, unichip get me, just so I know for the future?  I have a new manifold, sports cat and cobra style exhaust .

Cheers.

Again... You're going to be disappointed.
The most powerful n/a I've been in has had the engine bored out, high compression pistons, stage 2 cams, standalone ecu, open exhaust and intake and a bunch more gubbins... And it's still sub-200hp.

About 4k gets you to about 165-170hp (stg1 cams, exhaust manifold, intake, lightened flywheel, standalone ecu).
Is 4k worth it for 30hp?

4k will also get you a turbo install and over 220hp

The acceleration on the mr2 is ever great. The lack of torque is what gives most of that lack of sensation. I can tell you that even with a turbo, it doesn't blow your face off. Not until higher rpm... And the same applies to stock.
Maintain it well, set up handling well, find a nice b-road and enjoy the screams from 4k-6.5k rpm

[jonbill]

Tbh acceleration is overrated. You get used to it after a week or two and then start to wonder if there's a problem and you've lost some power.
I reckon stock power and going round corners quick is the way forward.

[jim_jiminy]

Thanks guys. Your right it's not worth it for 4K . I'll leave as is, unless I win the lotto!

I have my fiat coupe for acceleration, thats at 250bhp now.

Still the mr2 is much better handling, like a go kart! So much fun.

Re turbo, sourcing the individual bits certainly. Much easier just to buy a whole car with it already on. As and when they come up. (which is not that often to be fair)

Even though I do have a turbo, I agree with JB, I have a much bigger grin cornering than I do going quick in a straight line.
That said, does make for lazy overtaking, prod - surge.
And with the TTE turbo it is fit and forget, non of this piggy backing stand alone business.

Err... Tte has a piggyback haha

I have gone with the Apexi Power FC with hand commander. Just down loaded the instruction manuals 50 plus pages and now fitted the unit.
Started up with the self learning idle adjustment and runs fine (still need to road test) idles at around 900rpm may lower this
using the commander. Looks to be a great bit of kit.

Car is N/A with Cat stage 1 cams,PPE Header with 200 cell cat,Maxbore throttle body.

Indeed it does. But Mr Ts own, as forms part of the tte kit, I did not class it as a piggyback in the 3rd party sense. No visits to mappers required.
Hence fit n forget. Not fit n fiddle and fiddle and fiddle etc

Very true sir

Just for clarity. Re time stamps.
I was editing as patrick was replying.

@jim_jiminy
If you did fancy going down the standalone route, @boor
has a pretty cracking deal on his Apexi at the minute in the for sale section. With all required kit included.
The ApexiPFC is old but it works perfectly with the mr2. The 1zz version is just for 1zz.
