I've pretty much completed my F20A DOHC swap over a year ago and one thing that has always bothered me was how low on power it feels. Well, way, WAY before that I had taken it to a "speed shop" So they could finish up any loose ends. They were crap and neglected my car for the better part of 4 months.
One thing that I wished for them to do was to convert my auto JDM ECU to manual. The ECU is a PT2-900. When I got the car back in "working' order the check engine light wasn't on for the transmission codes and I assumed that issue was resolved. Well, after a good while I got curious and decided to look at the ECU and it looks like they did nothing to the ecu. So it got me wondering what they actually did to my car to not show the check engine lights for the transmission. (Yes the check engine light works.) I even got rid of certain exhaust components even though it wasn't the issue. (clogged) Got a prelude upper intake and a bigger TB and still nothing, sounds good though. The engine sounds STRONG and their is no weird noises. Compression is good. I'm just out of ideas and I'm leaning more towards the bozos that put their hands on my car.
TL;DR
Asked a shop to convert my JDM PT2-900 ECU to manual to allow it to run correctly and to remove the check engine light. The ECU is untouched but the CEL is gone. What the hell did they do? Car accelerates like crap.
>>SPECS<<
93 Accord EX
F20A DOHC w/prelude upper intake plenum and a 66mm TB
Manual Transmission swap - P2C4
Untouched PT2 Auto ECU
No check engine lights?
Any insight would be much appreciated.
The ECU:
The area that should have been modified.
