Here are the pictures. Ecu location is plastic, so ecu is not touch to chassis but ground connected via ecu wirings.

Ok, I will attach pictures in a day or two.

First I start woth 0.032inch and it misfires than I started to reduce the gap. With that much gap, engine misfires when boost comes on. I know that it should be around 0.03-0.04 inch but the only gap which doesn't misfire is 0.11inch. At 0.04 inch I think it will misfire too badly. You want me to tr...

I tuned a b16a turbo with hondata cpr and I'm using bkr8eix spark plugs. When boost comes in engine starts to misfire (at 0.023inch plug gap), then I lower the gap to 0.020inch and it doesn't help. After I gapped the plugs to 0.011inch gap engine runs great, but I think that there is something wrong...

I check it yesterday night. Gorund at a23, igntion power at a24, icm at a22 and altc at a16. I did the troubleshooting also every step is ok. Traction control wirings is also wired to a23 and a25 does it cause to this ?

On thermostat housing. We are using k20 coils.

Ngk bkr8eix and also I tried ngk bkr7e (which is normal copper plugs). Both plugs works fine with 0.011inch gap, and I leave the bkr8eix on the engine.

You are right, but if the header or exhaust leaking my external wideband sensor should read much more lean because I attach it with a tailpipe on the tip of exhaust. Am I wrong ?

Both cars are stock k20a with stock injectors and stock fuel pump. For the first car's calibration, those fuel numbers are for show the fuel numbers are high but datalog shows a lean mixture. So, after tuning that are not that much high :) Some of the calibrations are for test purpose and they are n...

Today, I tuned the car with external wideband oxygen sensor (innovate lm2) and air fuel ratio is ok, but on flashpro manager airfuel ratio doesn't change again. I don't know if there is something wrong with the software version or both car's oxygen sensor are broken.

ignition cut, if possible.

thanks.

any news? hondata spunkster?

Are you sure? Because it seems like works very well on closed loop. I will test it with innovate lm2 external wideband sensor in two weeks.
