Hondata

- 2000 MR2 Spyder with stock 2004 k24a2/accord cable tb
- version 4.5.9
- PRB ecu
- tsx stock calibration (attached)
- header and exhaust; no cat; PLX wideband wired to ano 2
- purchased november 23 through Healtoe
- finished the swap and the car is running so rich I have to pull 40% fuel to idle.
I have noticed the CLV is very high for idle and the MAP is relatively high as well.
When I mostly covered the iacv inside the tb, the car starts to die (looking for vacuum leak), but difficult to cover completely. I removed iacv and blocked and had the same issue. Cleaned it well and it was spinning freely and reinstalled. no change
I can't think what to look at next, but I feel it is caused by the high CLV. I also noticed a negative ELD of -14.06A, but I'm not sure what this means.

Your battery voltage seems to be fluctuating a lot and should be more stable.

Ok. I have added 2 ground staps for a total of 5 just to be sure.
1 from trans to chassis
1 from righthand engine mount to chassis
1 from valve cover center to chassis
1 from wire harness to valve cover post
1 from intake manifold to chassis
I did not see much change in voltage range, but I guess I didn't see a lont of fluctuation to start with. Only when it dips to 600 rpm.
Is there a good example I can review? What else can I check?
the ecu is on rubber isolators mounted to the chassis behind the seat.

Thanks
