"It does very little", wow, that is strange. Dave, what software did you download to access the computer? I looked back thru but maybe missed it. Do you have the EMS stinger? I need to check my TPS someday, after all of fabr and DS's comments. Are you bringing your laptop to LS with you?

The old saying,garbage in =garbage out really applies to EFI. this would apply if it had a O2 sensor. not to talk down Outfront. but john down right said,, A O2 probe was just going to burn up on race fuel. no need to put it on. I do not agree with this! I have ran O2 probes before with race fuel and had no problem. this is somethings else I found strange. I have the wiring for the intake air sensor but the Engine did not come with a sensor. programing seems to be set up to use it. here is my thought on this. one step at a time! get the car to run right. then start asking why. oh ya Johns response to the TPS being bad. it really does very little.?!?! Then why put it on at all! HA ha ha

Well, not too strange depending on the setup really..TPS is used for determining an "engine state", for example like WOT, Flood clear, DECEL fuel cut, closed loop idle control, Launch control enable, idle timing, and accel enrichment IF it is setup to use it. Some do accel enrichment as MAP based as I have done in the past with a screw type supercharger, instant boost needed a more defined control for accel enrichment. A combination of TPS and MAP can be used on some systems to do the job. On the most basic of builds if I don't have (or want) closed loop idle or decel fuel, the only thing the TPS is doing is flood clear. Not saying this is the rule, just that there is more than one way to skin the cat.
