Hondata

So I did a swap for my buddy, its a OBD1 B16A (Japan spec) and with his JDM ecu he got with the swap everything runs fine But it does have a check engine light. So I brought over my Chipped P28 (US Spec) ECU with a Hondata S300 and plugged it in, The Check engine light code was for the knock sensor. Which I ended up wiring in. But regardless when I plugged in my ecu (chipped P28) his car essentially goes into limp mode. (see the video below) This video is obviously taken while the car is not moving, however when the car is moving it does the exact same thing. and this video is taken with the throttle completely pinned. (Im not fluctuating the pedal at all) Ive done 4+ swaps before and I have never ran into this issue. Anyone have any advice? AS you can see in the Video, there is no check engine light on, on the dash, and The Hondata Smanager even confirms this.

I know it is not a problem with the ecu itself, Becuase when I put it back into my car and I use stock gsr base map that came with the s300 (preloaded) it works perfectly.

I havent looked at his car in about 3 weeks (he lives far away) but I will be working on it tomorrow and was seeing if anyone had any guidance with this issue.

Wiring in a knock sensor will not work with a P28 ECU as it does not have knock control.

Without datalogs and calibraitons showing what is happening it is impossible to tell what the problem might be.

i understand that a p28 does not have knock sensor. the fact that i can disable the knock sensor in the smanager voids the possibility of all this being caused by a knock sensor amirite?

If you say the s300 and p28 work perfectly in other vehciles but not in this car, then the problem lies with this car, and most likely with something in the wiring of the vehicle.

Attatched I have the datalogging of the s300 running with the vehicle for about 40 seconds. I am almost certain something is wrong with the wiring because when I hit the accelerator the rpm gauge essentially goes to zero. and when i let off the gas it rebounds back to normal rpm.
