Got an annoying little TPS issue.. When I first start the truck, the TPS idle point is about an ADC value of 170, as I run the truck, the idle ADC value drops down to 150.. Problem with this is it messes up my maps.. If I manually set it to 170, as it warms up it stays in idle mode waaay too long, if I set it to 150, it prevents jake mode from engaging
Wondering if anyone else (who's implemented TPS) has closely watched the TPS readings as it warms up and if it's just something funky happening in mine.. I'd buy a new one but I'd like to know if that's the real problem first
Cold things conduct better than warm things ?
Yeah, but that's the reason that it's a variable resistor with a hot and ground.. besides there's only a minute amount of current going through it... I dunno.. If it keeps giving me grief I may add a microswitch to it and only use that for a lot of the logic.. I'd much rather not though
TPS < && RPM < = idle
I'm using a slow moving average rpm with a faster computed rpm then average them together to get something that is stable, and slow, but fast enough to know when I'm idling.
Yeah, I think I'll do something like that
