Got it to idle......kinda
Hey all, I'm running MS2 with 2.891 firmware. It's all hooked up on a test stand with a 5.0l cobra engine. My issue is, when it starts up cold (100 ish, live in las vegas) it idles great, but as time goes on and it gets warmer it starts to surge, but only if I snap the throttle. Now, my narrow band O2 isnt working for some reason which i have to diagnose. Also, if I try to open the throttle just a little bit it makes no difference, but if i go to about half throttle, then all the sudden it takes off like a cuddled ape. So, maybe my something is up with my TPS vs. kPa table but I'm not sure. Any help would be greatly appreciated. I'll attach my msq file also.

Re: Got it to idle......kinda
Ok, so I got it to idle alot better. Found my idle screw was too tight and was holding the tb open a little too far thus leaning it out. So, now I just have to work out the AE and play with the VE table some more.
