Hi, received my cable today to do a scan. I Used the win program as I haven't tried loading or importing bins etc
My problem is that the car idles high and gets higher as it warms up. My iac counts started at 15, and I adjusted the idle screw to get close to 30.






Closed loop

It looks like you're looking at 160 baud data. Basically useless. You need to be looking at 8192 baud data.

The BLM data doesn't mean anything unless you know which BLM cell the ECM is operating in. 160 baud data will not tell you that.

I have noticed in other people's logs that INT and BLM are always 128 in 160 baud data. Is that just me or is that real?

Ok, how do I change this?
The 10 resister is still in when I obtained the data
Thx

Your idle will increase to about 1000 when you plug the cable in.

What do you think of Maf reading? It's only idling here but kinda low reading?

DanielRicany

Hard to say... It doesn't appear that you're in closed loop in this log so I can't compare it to the BLM.

Mine is pretty decently modified and it gets about 10 gms/sec at 1000 RPMs. I imagine a stock car would be lower because of reduced airflow.

According to the other tabs it's in closed loop , I waited for this to happen.
My iat isn't on right now as I'm running headman headers and that pipe running to previous exhaust isn't used.
At one point the blm number was at 120 not 128

DanielRicany

Mine does that too sometimes. The BLM jumps around a little bit but that's not enough to be worried about. The ECM can correct between 108-160 BLM.

Hi, ok I did a few more logs and I'm pretty pumped on getting the data saved now . Just been playing with idle so far, hope to get out tomorrow with the gf so I don't crash it or put it in the ditch reading numbers 😄
So far it's been winaldl but I'd really like to try tunerpro, but don't know what adx or extension file to put where.
Mines a 1988 l98
Yay!

Had a great night, up and running tunerpro rt 👍
Now I made a recording and going through the data. One thing I'm noticing is that the tps values are low and not changing as much as I thought they would.
Thanks for the links!

Billygoatkid

Yup the tps has dead spots , very interesting!
Thx to all those getting me set up to run tunerpro !
