It's not as simple as just chipping!
Anyway, the ECU on car can't be chipped (as far as i'm aware), which means you need a piggy back or replacement 'other' ECU.
Piggy backs known to work;
AND then you have to have them setup properly on a rolling road by someone who knows what they're doing, that ain't cheap either!
Even then you won't see dramatic improvements like you get when chipping a turbo charged diesel like the chipping business relies on.
With this engine you have to visit intake and exhaust too, and then forced induction if you want anything more than 165-ish bhp.
Believe me, there's quite a few of us who have explored all possible routes to more power and there's a wealth of experience written up in this performance section of our little meeting place here, all you have to do is look.
FGrob and myself have taken Normally Aspirated quite far without major modifications to engine internals, sjspitz is working on taking the 1zzfw engine even further. But go beyond the standard unit and it starts to cost a lot of money, then there are the 2zzge conversions (that nifty Celica VVLTI 190bhp engine), and a couple of very nice V6's. Turboes are around too, the late C2 kit, Hass kit, Power Enterprise kit, Top Secret kit, TTE fitted kit, Apexi (laughably called a kit), Thor Kit (which we've seen precious little of) and modifications of all those kits too because none of them are perfect and all have things that can and have been improved upon in various ways.
Then there's the Rotrex super charger, and the mythical CarverCharger over on spyder chat. But the supercharger kits are struggling for reliability and the turboes have been around long enough for people to make them more sturdy or know an advanced maintenance schedule.
I suppose what i'm trying to say is, don't buy an MR2 nd just expect to cheaply buy a chip and improve its performance - it's just not that simple!
For me, i'm very happy with my 164bhp and 133lb/ft and love the noise it makes. I'm concentrating on fixing the camber problems i have and improving air flow to the intake - just to iron out little imperfections i feel i still have. AND restoring my precious Ducati onto the road because although it's a pain getting into all the gear to go out riding properly, i'm finding i miss it now.
Cute & fluffy animals were definitely hurt during the production of this post, there're plenty more where they came from.
