E-manage Anti Stall...

Recommended Posts

It's for MAF based cars with Atmospheric BOV's. It's not required at anyother time AFAIK. Basically it clamps the Airflow reading when you let off the throttle to the levels that you find at idle...this makes it go lean as it should instead of trying to chuck in a bucket load of fuel for the air that's been metered and then dumped out via the BOV. So you ned to know warm idle voltages/cold idle voltages and to have your throttle calibrated correctly.

 

I can go through my set up with you some time if you like...it's different on a VVTi and a UK car though.

Awwww, When you said anti-stall I thought you meant like we have in F1. Drop below a preset certain number of revs, and the anti stall cuts in, revs the engine and dumps the clutch.

 

Funny story actually. A certain recent podium achieving F1 teams technical director, borrowed a previous employers car to go up goodwood in. (Can't remember if it was the festival or the revivial). Anyway, First run, take's it steady, get's it to the top, it's a bit tight tunrning around, and there's lots of crowd. Anyway so he's inching this thing round when he lets the revs drop a little too far. The tyres light up as the anti-stall cuts in, and fires him off to the crowd. He's got his foot as hard is it will go on the brakes but 900 ponies take a lot of overcoming, and he's headed crowd-ward. It screaches to a halt as he manages to grab the clutch, inches away from blasting into lots of spectators. They think it's brilliant a start applauding and shouting. He's shitting himself.

He wrote the car off on the next pass about 10 yards from the starting line. "Ran out of talent" was the phrase he used. LOL Imagine that phone call

"err Eddie, that car I borrowed....."
