Hondata

hey,

i've got a 94 civic hatchback with a 97 prelude engine. I just got my hondata stage 2 the other day, but I am unable to tune it. The problem is that under a load the car will not drive well. It moves then tries to stall around 1K. The engine will rev up fine when it's in neutral, but just not under a load. However, my old P28 that I used with the car worked fine before installing the hondata. The hondata ecu was programmed at the dyno to use a base setting for the h22.

After inspecting the engine I have one idea:

I inspected the timing belt and the exhaust cam looks to be 1 notch on the timing belt out of sync with the intake cam. The flywheel does not have a mark to check the timing. I don't want to have to rip everything apart if this isn't likely to be the problem.

Could this be a possible reason for this problem? Could there be any other possible solutions? I just swapped out the distributor from an obd1 prelude and that fixed the other previous error codes.

If the car revs fine with it in neutral, I doubt your problem is related to your exhaust cam. I would say your new distributor may be bunk, but again, if the car acts fine in neutral, this probably isn't the case. I don't know if your car has it, but some people have had problems with the ELD in their hondas when running hondata. Search this board for ELD problems and see what you find.

thanks for you input. I decided that the only difference when the car is moving and stopped is the load and the speed sensor, so i unplugged the speed sensor. Bingo, the car revs in gear just like it revs in neutral. Does this mean that the speed limitor is set too low? Could the speed limitor be malfunctioning even though it worked properly on my stock p28?

Thanks,
Jon
