i just snagged a super moniter from a beat up supra at a junk yard today and i am going to hardwire it into my 89. i was wondering if there is anyway that we can manipulate the input that calculates fuel economy to work with 550 injectors. it came off a n/a so the mpg's will be way off. which wire does it use from the tccs to calculate mpg's? what is the difference between the n/a sm ecu and turbo sm ecu? maybe a simple resistor change in the ecu could change this(similar to 3p's tccs egr map change by removing a resistor). thanks

This is a good question, and I'd like to know about this too.
My car was originally NA, and the supermonitor obviously doesn't show a valid mileage estimate,
as I have a 7mgte in it with the 440 injectors, and it shows a mileage I would guess is about 30% too
optomistic. Would like to hear more.

still have mine. yeh, good for checking codes, keeping track of oil changes and there is like a track/trip timer thing which is kinda neat. if i didnt have one i probably would pay stupid money for one though. i mean, its not THAT great.
