Hondata

Try the ECU in a known working and good vehicle.

I'm trying to line one up. We live in the middle of no where. Trying to talk a guy with a type-s into it that I dont even know. And as far as k-swaped, its problably the only one within 100 miles atleast. :(

Have you atleast heard of anything ...

Bingo....

s far as it being rich, going back to see my tuner next week.

And I would like to add, the voltage is steady at the battery, fuse box, and alternator regardless wether the o2 relay is plugged in or not. Thats why I feel it may be a problem with kpro. If you know of some other places I should look for the voltage drop (where kpro gets its voltage input) Ill be ...

Both datalogs show a problem with the alternator / wiring / grounding / battery voltage. This is fairly common with engine swaps. The battery voltage should be fairly steady between 13.3 and 13.8V, rising as it gets colder.

You can't measure the DC resistance of the wiring with enough accuracy to ...

I ohm'd the main wire from the alternator to the fuse box. It was .4 ohms. I then ohm'd the 3 wires that go from the alternator green connector to the ecu. Each one was between .1-.2 ohms. So in conclusion the harness is good. I also did a voltage check on the cable from the alternator to the fuse ...

Hondata, checked the fuel pressure under full load. It holds 43 psi solid the whole time. Lost in the sauce again. Going to look at the alternator wiring later tonight. Everything was tight on the alternator when I checked it earlier but Ill trace everything back to the ecu.

I looked at the fuel pressure on the 2 step, held rock solid @ 43lbs. Regardless, tonight Im going to route the gauge into the cabin to see what it does under load.

Also load tested the battery. It passed. On the battery I'm getting 14.3 volts. On the alternator I'm getting 14.5. On the KManager Im ...

Factory wideband generally does not read below 11:1. The only vehicle fault I see is that there is a problem with the alternator or alternator wiring. According to the factory wideband the vehicle is running quite lean at cruise, and the MAP is fairly high for that speed, which may indicate the ...

I completed a few logs. Idle, Cruising in 6th, 2- 3rd Gear Pulls w/Abel Tuned Map, and 1-3rd gear pull with the 9PSI JRSC KManager Map.

With the KManager map, I still got knock and super rich AFR's where as before, the map was really lean with running 11psi. My UEGO Wideband said 10.0s, and the ...

I did leave him a message. I live 400 miles away. I don't believe its the tune.

Heres my Calibration. Working on getting a datalog.

Last friday (4 days ago) I had my car tuned at Abel Racing. He used a shelf ...

I've done a little more research. From what I gather, closed loop is for normal driving and the ecu switches to open loop when going wot into boost. My car has a jrsc on it too.

Don't understand why my car is running so rich now after getting tuned.. It was 11.9 all the way across the board ...

Eg civic w/k20a2 and kpro.

I just got my car tuned and my car doesn't have o2 sensors so I'm in open loop and now my tune has already gone to shit and the car is running rich as hell on wot pulls. Not to mention, normal driving even after some road tuning still kinda sucks. So i need to go closed ...
