MS 1 tuning

[MazdaNoob]

Good stuff !

[KAinjection]

I figured out how to get closed loop idle settings and they seemed to work then the car died when the engine warmed up and after restart the engine was back at high idle again. Any ideas?

Also I am having trouble with my cold start, so could anybody that has a good tune post there settings for me to compare to. It seems like I am adding too much enrichment compared to others I have seen.

[MazdaNoob]

yeah you DO NOT want to see my cold start enrichment settings LOL .. puts me in the 10's atm

[KAinjection]

I still wouldnt mind seeing it if you can find the time to post it up. Decided to not run closed loop idle mode since the RPMS wont drop to normal idle after the car warms up.

Anybody want to view my short log and tell me if its normal looking? I know the AFR on Accel is too lean, but I am taking care of that.

PM and I can send it through email since I cant attach or upload a file to the board

[MazdaNoob]

Sure. I'll send the whole tune ( project). Later tonight

New problem occured last night. I think this is related to my occasional misfire at idle when warm and it sometimes misfires very badly at cold start. It has also been starting very hard lately. Cranking forever before it finally fires.

Went to move the car last night after it was all warmed up. Was actually idling nice and smooth. Car stalls and will not restart. I did not have a chance to check anything yet but I am 100% sure its not getting spark. Cranking forever the wideband reads richer and richer, flood clear mode and it will eventually read "air" . tunerstudio is showing the tach is working and showing cranking speed. Pw and duty cycle all appear fine. The tach in my cluster on the other hand is not showing anything while cranking. I think the coil died, but I realize it could also be the ignitor, distributor, or the MS. Any suggestions?

Weren't you having ignition setting issues? ( haven't got my laptop back from my kid yet to send mine) improper stings could easily fry the igniter

Yeah I wasnt sure where it should be set and had it on 3.8 dwell time for a long time before recently changing it to 3.0 based on other cars that have single coils since I couldnt find a specific answer for the bp unless its for a miata. Going to hook the stock ecu back up temporarily to make sure its not a MS issue.

[KAinjection]

Well I just hooked the the oem ecu back up and connected the harness to the VAF with a screwdriver jammed in the door to engage the fuel pump and it started up after a few cranks.........either my settings are very screwed up or something in the MS failed.

[MazdaNoob]

i had that once .. kept flooding out .. was my wideband settings iirc

got so bad it actually killed a set of plugs ( let alone my cat lol )


pm me an email addy
