microtech + FD TPS
I'm having hard time getting ECU to read 0% throttle position.
for those that have calibrated FD TPS with microtech, did you have to rotate the TPS physically or only adjust software settings, or do both? thanks in advance. |
You'll likely have to rotate it physically a little. Get it as close to zero physically as you can, then use software to adjust until you have the *.
Also, make sure you are using the full range TPS. The FD has two, one is a narrow range. Not that it really matters though because unless you use TPS for your PUMP settings, the Microtech only uses the TPS to tell when the engine is idle. |
My question is if you get it calibrated to 0*. On idle what if it doesn't reach full range like 92% instead of 99% like it should. Will you be losing hp? I have a FD and the best range I can get is 0*-92% at WOT. I also have FD but with a Plug and play lt8.

Again, the Microtech only uses the TPS to determine when the engine is at idle. If zero, then idle. Anything but zero = no idle. Unless you are using the TPS for accel enrichment which is not a default setting.
So it's more important your TPS reads zero vs. 100%. Fundamentally you could have a switch instead of a TPS. Microtech doesn't care. The Microtech TPS calibration, like most of the functions of the antiquated ECU, is locked down. You can only adjust the zero point. |

update: turns out tps a forum member sold me was bad. Installed one from autozone, and it works fine now.
