Hondata

J1 was jumped on the original ECU, but not the new one. I jumped it, and solid CEL, no blinkage :/
Should J12 be populated or no?

Hey Spunkster.

I ended up moving over the OBDii > OBDi adapter connector as well as my socket and chip from my original Hondata bought P28, and put it into an unmodified P28. I had to move over the 4-pin s200 connector as well.

I thought I was in business as I had no CEL and VTEC switchover ...

Thanks for your reply Spunkster.

No other modifications required, then? I thought I recalled reading in the past that some P28's might need a certain resistor removed.

I don't anticipate moving a socket or the adapter over to be easy, but we have a very nice vacuum soldering station that I am ...

I have an S200 and P28 ECU purchased from Hondata. The ECU took a dump and I was hoping to simply swap my chip (and OBDIIa conversion PCB) over to either an unmodified or socketed P28. I want to make sure that is possible and also know what other modifications are required. Obviously I'll have to ...

RESOLUTION (repost again due to delete):

If you purchased a defective Hondata ECU (like me), and you have this problem, you need to jumper the TPS signal pin to PCB terminal D11 as shown in the schematic posted.

I have pretty much ruled out the vehicle/tps/harness, because I am measuring voltage at the ECU, backside wiring harness connector. I don't think it will change measuring internally at terminal-PCB junction, but I will try.

Sorry I didn't mean P73, I have a Hondata-branded ECU module, OBD1 of ...

I don't have the sensors swapped.

I am at .495V closed. I didn't measure at the backside pin inside the ECU, but assuming I have correct voltage there.

If I don't, great.

But if I do, there's no reason for it to fault before I even press the pedal.
In this case, can Hondata share any schematic of ...

Have you tried the ECU in a different car?

No. Don't have one. But the stock ECU doesn't fault in this car...

But as an update, I found out that my TPS sensor's pinning was reversed. Actually, the molded connector was upside down compared to the other two I had. So it was 4.5V closed and .5V ...

s200, ITR.

-I have tried 3 TPS sensors, all calibrated.
-No TPS fault with stock ECU.
-I have a CEL 7 (TPS) that won't go away.
-Vsig .68V open, 4.75V closed (or whichever way around)
-Sensor supply @ sensor is 5V dead nuts.
-Logger reads 26% (1.5V) no matter what.

I am guessing that this is the ...

I began throwing a code 7 after installing my hondata.

I have tried setting the TPS sensor pot output to .45V and .5V closed throttle and I'm still throwing a code. Is there anything else I can do short of trying a new TB/sensor?
