Manifold Air Temp
 

Manifold air temp shouldn't be reading -14* F right?

Where should I look to fix the problem?

IAT sensor wiring.

What IAT sensor, stock or GM? Could have wrong sensor for the easytherm settings you're using.

Stan, if you want to I'll help you knock it out tonight. Right now. 404.xxx.xxxx

CJ, it's the PNP. No easytherm for us. :-)

Understandable. Get him to fix his sig so i remember in the future. Then again, being the PnP i bet there won't be a future. Looks like i need to live around atlanta. Not enough people near me in TN with megasquirt going on besides Al.

yeah and even fewer in alaska hurry up and get back chad :D

Crisis resolved. Stupid JRSC IAT resistor fueling. :robert:

Yeah, how stupid is that? I didn't even think of it... it took the phone call with Ben to remember it. It was fixed in less than 5 minutes....:)

no way he had the old resistor trick going on to make him richer :gay: damn i almost forgot people did that good times

Darn Band-aids ;)

Glad you found it Stan! Thanks Ben!

I hope that shows to anyone considering the "resistor trick" what a bad idea it is.

I had always ass-u-me 'd that the resistor lowered intake temp on a scale. Like took a percentage or a fixed value off actual. I had no clue that it would just lock it in at such a stupid value. That has to be one reason why the JRSC guys get such crappy mileage for 145 rwhp.

nope. It's tells it full cold no matter what.

I used it before to allow for advanced timing on my altima, cause otherwise the ecu would reset ignition timing regardless. Which resulted me in a 15.7x 1/4 mile, with no other mods :gay:

157.8, thank you very much :D

I bought the car with the supercharger already installed back in 1997, and that was the trick of trade back then. I don't think it's part of the instructions anymore with the Powercard and other better band-aids we have at our disposal now.

This brings up a whole new issue for me... I wonder what kind if mileage I can tune now... 30? 33 mpg? I wasn't even thinking this until last night. hmmmmmm :)

I also bought a JRSC powered 2000 and it has a PowerCard setup (and I HATE it! and am looking for something better now). I have a ScanGauge in the car and notice my IAT drops to -40 when hitting the gas. Is this the band-aid you guys are talking about? Would I get better MPG with something better?
