What form of load recognition do most of the pro import drag cars use?
I'm having a debate with my freind, and he seems to think that most of the pro car's use a speed density or Alpha-N type of load recognition, where as I think most just use the standard 5bar MAP sensor, with temp corrections like most aftermarket ECU's.
For those who don't know, the Alpha-N is a system that will log the timing, fuel, and throtal position maps into a specific table based off the tuning process. You tune for max power without detonation, and it saves those values. Then it uses those saved values and throtal percentage to run the motor. I have absolutely no idea how well this method works in real world conditions.
But I have simply seen more pro cars using standard 5 bar maps than anything else, for me to beleive they use this form of load recognition.
Any ideas?
Thanks,
Bryson

MAP Sensors Homie...how else with boost?
Alpha-N works with All-Motor cars...I did a K20 with Motec, no MAP Sensor at all.

Thats exactly what I thought, but this guy bought the $1300 Alpha system to work with his Motec.
Waste of money in my eye's.

What's an "alpha system"?
"Speed Density" and "Alpha-N" are two different ways of calculating load. "speed density" uses a map sensor, while "alpha-n" is generally TPS based. There's no system or anything, it's just how you configure your software.
Bryson, your interpretation on this stuff is not right, do a little more research on the different terms and you'll probably understand it better.
Both systems use temp corrections and such, just different way of calculating "load".

This is the $1300 dollar system he purchased:
I never said the speed density and alphaN are the same means of load measurement, and my interpretation is fine. What I was asking is what form do the pros tend to use...? Thats all.

That looks like a cheap fuel management system named alpha n.

Yet he say's he's using it with his Motec M8...
?
From what I gathered, it will change the maps MAP load values to the TPS values.

sure does....
no map sensor. tps/rpm only.
I'm sure you won't be seeing any pro's with that system.... lol...
