newbee question
Ok....I have a slightly modded 85......no air/egr bigger tb and roller rockers....had it "tuned when I built the engine up.....Now the wife buys me a laptop and wants me to get a program to get data from the car...not very computer friendly but with the help of a teenager, managed to downlown winaldl and get it to read data....now i'd like to know if these figures are valid......haven't got into it enough to know what all of them mean yet....here are some samples...
CT 167
TPS 28
INT 122
O2 137MAT 141
BLM 150
O2 CNT 50,14,241,227,193
NAFB 193
BPWB104
RPM 40 (actually was around 900)
Just plugged it in and started the car.....these are the figures that came up.....
couple of questions...."dash " display corresponded with the correct rpms but it was higher with the unit plugged in
also had to change the baud setting to 4800....2400 only other option...only collected data on 4800....
it's win aldl....not sure what it does or what it can do yet...really just a newbee at this......all comments and advice would be appreciated....tried to download tunerpro but just couldn[t get all down...something about bin files and adx files.....got winaldl to work so trying that....thanks....Paul

Your blm of 150 means lean and should be closer to 128. Maybe you can turn fuel pressure up to bring that number down. However, a single snap shot isn't fool proof, and should be observed in a myriad of conditions.

thanks....right now i'm interested in just seeing numbers that should be within parameters and hopefully correct....On the advice of FIC at the time, they recommended 22# injectors that needed 43.5 up from the stock 38 so I turned the fp up at that time., but i'll recheck it.....

CT 167 / 167F is not fully warm, or a 160 t-stat.
TPS 28 / usually the TPS reports .54 to 4.5 volts, so I'm confused a bit.
INT 122 / Intergrator is the short term fuel trim, and the driver for BLM adjustment.
O2 137 / O2 volts should go rich (above .450) to lean (lean) in constant adjustment of fuel. looks normal.
MAT 141 / As read at plenum, and this temp tells me it was above 70F when recorded.
BLM 150 / previously discussed. Adjustment from 108 to 160.
O2 CNT 50,14,241,227,193 / my guess would be recorded cross counts, or O2 switching from rich to lean.
NAFB 193 / ??
BPWB104 ? Base pulse width of injector, but I don't understand reported value.
RPM 40 (actually was around 900) / Must need a conversion to understand?

Have you seen this?

eveything helps...eventually i'll read the instructions.....i'm a fairly quick learner, just think ( or thought) computers make good boat anchors...learned alot on the tech and performance side...i'll be gleaning what I can from the scan and turn forum....thanks ....Paul

The RPM is divided by 25 because it won't fit in an 8 bit binary number, which only goes up to 255.
Some cables have a 10K resistor built in. That will put the ECM into "10K mode". One of the side effects of that is that it will fix the idle speed to 1000 RPM. Notice that 40 x 25 = 1000.
