(it was a swap of the IS-F engine)
Direct injection as the only fuel delivery wasn't a problem for them, but the combination they found in the IS-F was a problem.
Waiting to hear back on BRZ/FRS developments. |
Thanks.
It's honestly amazing how much ground I've made already with this car and we have the connectors, dual AVCS, and the DBW stuff already worked out. Unlike the IS-F there is much less integration with the FRS/BRZ as far as the CAN systems and the transmission (We are not really working towards the Auto integration yet just the manual).
The CAN bus stuff can be difficult and we've just about got it all dialed for the 08+ STis it will also require work on this car. Until we fully developed the CAN integration on the STi we ran the OEM ecu in parallel so that it could report some of the dash functions like speed and coolant temp. It's possible on the early release of the FRS/BRZ ECU we'll do the same. If demand doesn't materialize then it's going to be hard to justify the engineering costs associated with cracking all this stuff and for many manufacturers it just boils down to dollars and cents.
I don't want abandon the NA guys as I I've discovered hidden power in the dual AVCS systems for the STi and I could likely do the same for these cars. With integration of the Hydramist water/meth system and or race/E85 I think I can get substantial power gains. For high power NA to work with the high compression however we need those direct injectors.
