Hey guys - I have a CEL, obviously, since I use MegaSquirt standalone ECU but still have the stock DME in there doing the tach and other stupid stuff. Anyway, I did a stomp test to see what codes I am pulling - I only have 1! Its kind of funny, I thought it interesting because I have no injectors, no coils, no temp sensors, no TPS, no CPS, no ... etc hooked to the stock DME, and the only thing it complains about is "1261 - Fuel Pump Control" lol. I think it's mildly hilarious. I mean, imagine if I did have big issues with my car and the fuel pump was whack - I go through and fix the fuel pump and am real excited to drive my car... then BAM all the other codes become apparent ... lol

Make sure you don't have fuel pressure problems. I'd hate to see that bad boy lean out.
How much boost is this thing making?

Ross - the fuel pump warning is because the stock DME isn't controlling the fuel pump relay any more - I have excellent fuel pressure :)

This bad boy is rich as all hell... 10:1 at peak boost... better safe than sorry, but it's freaking fast before I even lean it out!

Just about 10 psi from a turbo that flows 72#/hr.
