LS4 / F40 swap - fieroguru (Page 212/212) fieroguru SEP 12, 07:50 PM quote Originally posted by pmbrunelle: I am dissapointed that the Haltech is not "torque-based", in the sense that the accelerator pedal doesn't request a torque, and then the Haltech would figure the required throttle opening and boost pressure. I'm working on a (non-Fiero) naturally aspirated project with a Haltech Nexus, but I want the accelerator pedal to roughly represent torque, so (in conjunction with a MAP vs. RPM vs. TPS correlation) I need to do some calculations in Excel beforehand to populate the pedal-to-throttle table. The feature I wish the NSP had was misfire detection. For my application there are several options to match power to available traction. I just need to take the time to play more with them. pmbrunelle SEP 13, 09:50 AM There is an "RPM derivative" channel in the firmware. Probably not at runtime, but maybe in analysis of a datalog you might be able to see something? I guess that misfire detection is harder with the number of cylinders you have. fieroguru SEP 13, 07:37 PM The brakes are done, and the total weight removed between the springs, lateral link brackets, and brake rotor swap is 8 lbs in total, 4 per side. The new rotors also fit behind my old set of 16x7 35ET wheels: While working on the drivers side, I found the tripot boot split, so removed, and disassembled it: Ordered a new boot, which will be here in a few days.
