data

I think:
1.af= air flow, yours is 5 grams per second = idle
2.L8= engine load 0-255 lowest to highest
3.INT= short term fuel trim, yours is 128, neutral reading
4.BLM= long term fuel trim,yours 143 lean, 90=rich 150=lean ECM adding fuel
5.ats= air temp sensor, yours 131F, death valley?
6.iac= idle air control, yours 26 OK, should be above 0 less than 50(just an opinion)
7.cc= cross counts, number of times O2 sensor crosses 0.450v switching from rich/lean, this number should climb to 255 then reset to 0 and restart
8.pl= I don't have this
9.sp= ditto

I was interested in getting one of these,i didn't know that they gave that much info.Which model number do you have and will it work if I have a mid 90's DFI in my car??

 

[Jeff@Ramcharger]

The only way it will work is if you have a piggy-back DFI kit and are still using your factory computer. If you are using a DFI computer, then it will not work. The part number you would need is SCAN2.

Hi guys!

Sorry to dig up such an old thread but i did a search on long term ecm and this one came up.

Anyway, i started up the TTA and the long term ecm reading is 160.

Can someone explaine for me why it´s so high and how i can get it down?

Regards from Sweden!

A BLM number topped out at 160 like that would indicate one or more of the following:

A vacuum leak, or a pre turbo exhaust leak.
