I recently had my top end rebuilt(d16Z6) and found out my stock ECU died at the same time my timing belt snapped(which is why I had to rebuild the top end). The guys at the shop replaced my p28 ECU with a p30. I guess they didn't pay enough attention and thought I had the DOHC VTEC model. Thing is I swear this del sol has never been faster. But now my MIL stays on, my speedo is off quite a bit and I am sure its running rich. I want to keep this ECU in the car but I want everything to function properly and lets face it, I love knowing my limiter has increased from 7440 to 8000ish. I haven't revved it that high but I have read mixed reviews about it with most saying its safe to rev to 8000 but not much higher. What can I do to keep this ECU and have my speedo, VTEC engagement, and fuel consumption correct and have the ability to rev it just below 8000 when needed? Please help.

Thanks in advance...

 

You probably are running rich. Do yourself a favor and get the stock ecu.

 

Still have it. It needs to be repaired.

 

Find one on ebay. P28 are so common, man..
