Maybe my idea of this adjuster somebody else will make one, and save somebody's engine on a cold night.

 

there are some trucks in florida that have run mid 11's with a stock computer.

The factory tune adjusts to much more than many people think.

 

Ya I heard of a few spaying some massive amounts of n20 too,
all without a chip, and with great success. I've often wondered WHY the factory computer or some kind of aftermarket computer, can't be put in and CONSTANTLY adjust for mod, elevation, and temp changes.

Sounds like you know exactly what your doing AZ, and that other toy of yours sounds HOT

It truly does scare the ever living schitt out of you when we all know a simple bad tank of gas can actually toast a brand new L motor. WTF is up with that )@$^(@$%(@$%(@$
I'm so surprised no one has put ANY time into getting the knock sensor figured out ?

I have been extremely lucky with mail tunes, I've yet to get a Dyno tune, (of course thats all about to change) but I totally understand AZ, and am very interested in your results. Best of Luck and please keep us informed.

 

Nice idea there

If you don't trust the "tooners" so much why not tune it yourself? That's what I decided to do, and havn't looked back. Check out modulardepot.com and look at the pro racer package.

I am sure you goal can be met, but I don't see any way the boost a pump is going to change your A/F like you plan. Your problem will come when the MAF pegs and the computer doesn't know the engine needs more fuel.

 

Like who, Mataus?? The factory ecu does adjust fuel levels to a point, but not to the tune of mid-eleven second trucks. Thats where timing plays an important factor and the factory computer cannot make timing adjustments. No slam , just a little Why haven't you been to towers lately?

 

With the boost a pumps they only switch on under boost increasing voltage to the pump , increasing fuel pressure , increasing ,fuel flow thru the injectors even if MAF is maxed out it going to put more fuel in . On my chevy i have an FMU that closes the return fuel line off to the tank under boost increasing fuel pressure to about 25psi, it was the most i could get and is ok for 8 psi boost but for 15psi boost i needed more fuel pressure, boost a pump turned up fuel pressure to 45 psi at max setting and you can dial it in to what ever pressure you want from your seat at 15 psi boost , 45 psi FP, wideband is at 10 A/f easily adjust my fuel to abot 38 psi i have a 11.5 A/F. And you only kicking the voltage up in short bursts WOT not like is on all the time. normal driving FP is 13 PSI until boost, then the boost a pump switchs on at 3 psi boost and above. this is what i have on my 454SS . Also looking into the MSD knock sensor monitor for the Lightning.

 

Maybe some tuners could chime in . I would like to know what they think

 

In fact it DOES adjust the ignition timing. Like the 4.6 engines, there is a sensor that picks up the "teeth" of the gear (it's actually not a gear) and is able to determine the exact potition of the crank. It uses the blank spot where there is a tooth missing as reference. By adjusting the position of the sensor (kinda like a high speed prox switch) either clockwise or counterclockwise around the "gear", the timing is adjusted accordingly. These have been used for many years on Mustang 4.6L engines, and I beleive Steeda was the first to come out with these.

 

TTT

 

There a guy in north florida doing it. Haven't been to towers lately since I live in Gainesville now and I'm going to UF there.

 

thanks! I didn't realize that.

 

He's referring to the aftermarket timing sprocket...NOT the mass air sensor.
