Stock Mach computer limitations????
I keep reading all this stuff lately about stock mach 1 computers and them cutting out at 6800. My old Mach 1 w/ eaton swap ran perfect all the way to the 7250 rpm rev limiter....I would always shift it at 7100 and run out 4th gear till it hit the limiter. What made that car different from all the people having issues with them? I know it was built in the last month of production, did they maybe change something right before the end? Build date 04/14/04

Re: Stock Mach computer limitations????
Why were you shifting so high?? Was it on a built or stock motor?

Once I said **** it and drove it like I stole it, I was trapping 123-124mph. 27k miles on the car in just over a year and never broke anything. I went through 4 sets of tires in that year. Cant put one through much more hell that I did with multiple DAILY visits to 7250 rpm. I have a video somewhere of me walking a hci c6 vette all the way to the limiter in 4th gear which was 158 mph with my tire/gear combo at 7250 rpm

Re: Stock Mach computer limitations????
158 mph in 4th??, I would think 3:55, even if a particular motor ran up to say 6800 rpm, couldn't you just get a handheld tuner and raise it??

Re: Stock Mach computer limitations????
Im confused now. He said he was trapping 118 at 6700 rpm which would be something like a 4.10 gear i would think. Then he said he was trapping 124-125 and running to 7250. But at the end where he said he ran the vette and ran up to 158 in 4th that must have been after a gear swap

Re: Stock Mach computer limitations????
Was it a stock eaton that was pullied or was it a ported eaton. Im asking because you said it made peak at 6800. I thought they usually peaked at a lower rpm

Re: Stock Mach computer limitations????
Here is the vette video. I was just supposed to be videoing the vette vs gt500. Thats why I start ahead and hit it late. But once I saw the gt500 dropped out I just kept going. I had already raced the vette before and drug him. But this shows how strong it pulled up top and that it never falls off until the rev limiter at 7250

Re: Stock Mach computer limitations????
My car has done the 6800 rpm thing. Once in a while it does it, then sometimes its fine. I usually shift at 6800 anyways, but it screws me up when it hesitates right as im shifting.
On a side note, must have been an LS2 corvette. A h/c/i LS3 should get your car pretty good

Re: Stock Mach computer limitations????
This would be correct, shift beyond peak so you are at or closer to peak in the next gear...= higher average power thru the run. Do a search for blkcloud and listen to him...his shifts and lack of mods will make you sick!

This is by far my favorite video from my old 7.5psi stock eaton Mach vs a 2.93 pullied ported blower Cobra that weighs 3400 lbs. Desipite being down 50 rwhp I kept up nicely.

Re: Stock Mach computer limitations????
I shift like that when in 4th. 456 gear kinda makes me to finish out the qt mile. I have cams and still make power at redline... I've ran it out to 7200 many of times. The only thing I worry about is the oil pump. :/

Re: Stock Mach computer limitations????
Ok, an attempt to get this thread back on track, although the other conversation was good as well. But, if I wanted to have the ability to turn 8k RPM, what computer would allow me to do this properly? What is involved with changing to said computer?

You can also use an MSD 6Mod to control the ignition while letting the stock computer handle the fuel duties. My choice would be the holley systemhttp://www.force-efi.com/holleyefi.htm. You can use the stock computer to power the dash gauges if you wanted to keep them. MGannaway, I forgot to mention the holley system to you the other day.
