How does the EMS respond once the MAP sensor is out of range (~11psi)? Does it cut fuel or spark?

TIA

it will try to cut fuel, but if you're a pimp like me, you can get around it....

Dude MASE...you seriously need to come out to So Cal again. My EMS is really pissin' me off right now. I'm about to throw it out the window. It was running fine in WOT yesterday but now its misfiring in boost. At first I thought it was the MAP sensor seeing over 11psi but I turned the boost controller off and it still does it. ARGH!!

At WOT 5500 rpm, it sputters then POP POP POP with a great big flash of light out the back. The ambient temperature is a lot different today than yesterday. I'd say the temp yesterday, while being tuned, was hovering around 80 degrees. Right now its about high 50's. Wonder if that makes a difference.

yes airtemp will make a difference, you need to look over your air temp correction factor table.


Dont boost higher than the stock map sensor can read, its not a good idea. but its really easy to get around it , just set the boost cut higher than what it can read.
