Hondata

I would suggest getting a wideband O2 and fine tune your fuel settings, I never got my engine running perfectly smooth untill I installed an O2 wideband.

so mail it off with the form and cashiers check, a few days later I get the ECU back ready for my S300 to go back in?

in regards to getting a new ECU and installing my current Hondata into it, I've found a potential ECU, but here's my issue, some of the parts are still soldered into the current ECU, am I going to have to desolder the tracks and mail them off with the S300 or can I just get the new ECU, remove the ...

ok, I checked all of the solder points on the ECU and they all looked ok, I resoldered a few just incase.

Durring my inspection I looked for leaky capacitors and found C21 and C24 were both leaking, I don't have a schematic of the P28 ECU so I'm not exactly sure what these 2 capacitors do for the ...

I went to another state for training and the clutch system went out, it took about 2-3 weeks before I could get the proper parts for it, and by then I had to have it towed back to my home state, so basicly the car sat for nearly a month and then it wouldn't start, I inspected the starting system and ...

car ran perfectly up untill a few months ago.

used multimeter to test power and ground/fuel/ignition system voltages under non-running conditions.

A1-3, A5 = battery voltage
A7 = battery voltage
A21 = 11.83V
A23 = 0V ohms 0.3 to ground
A24 = same as A23
A25 = battery voltage
A26 = 0V ohms 43 to ground
B1 = battery voltage
B2 = same as A26
D1 ...

ohmed out the harness and everything ohms good, although there is one wire that confuses me a little in the harness.

On the OBDI side of the harness there is a wire that goes to A7 (FLR1) and then it splits into 2 wires and goes to the OBDII side A15/A16 (FLR). A16 is unoccupied according to my ...

you can post it on here and wait a few days for some of us to review it, I would suggest doing a datalog with the tune and post it on here, with enough eyes on it someone might notice somthing.

still waiting on a response from spunkster.

one more thing, I decided to pull the ECU out to look at it this morning, and I get a constant red light from the S300 when I turn the key to ignition II.

the wire that's spliced into is SCS.

here's some pics

this was an auto to manual swap, there was 4 plugs.
