I have an 87 iroc tpi with a few upgrades. I got my datamaster up and running and I took a run the other day but there is so much info that im not familiar with, I was wondering if theres anyone here that I could email a copy of my run to so they could take a look and tell me if theres anything wrong or if everything is working right? I do have a minor idel problem thats been driving me crazy that I would like to hopefully solve but I would just mainly like for someone who knows what all the info is for and "should look like" to take a look and tell me if everything is working as it should. Thanks!!!!!

 

Humm is anyone using TTS Datamaster???

 

Dont assume the readings your getting are correct. I just talked to tts yesterday and they told me they do not have a program for 87 350 tpi,only for 87 305 tpi.They said if I did get it to run (on my 87 350 tpi) info would probably be wrong.

 

Humm thats good to know. Im looking at the download page and it says 86-88 y-body 5.7L PFI (L98) 8192 baud and I thought that it would work on the tpi cars. It does but I guess the info might not be 100%. I wonder if the dyno would still be correct? I did a run the other day and Im in the proccess of putting on a set of AFR's and a comp cam and was going to see how much I picked up over my stock heads and cam. Damn that sucks and is bad news!!!!!!

 

So, what are you using the Datamaster for/ i am assuming that its a data logger. Therefore, the size of the engine should not matter for the raw stuff. Such as, engine RPM, BLM value, Fuel Trim Cell (FTC), O2 sensor voltage, MAF reading, coolant temp, injector pulse width (PW), etc. Now, something like Air Fuel Ratio (AFR) might be calculated, and therefore could be wrong. However, the idle and drivibility can be fine tuned by the BLM value. You have 16 FTCs and a unique BLM value in each of these 16 FTCs. The perfect BLM value is 128. If you are between 122 and 134, you are well tuned for AFR on drivibility. WOT tuning should be done with a wide band O2 meter.
