Not for Nuthin' But Close!

Billy get yourself an HP Tuners setup, you’ll have infinite tuning abilities from your laptop. Basic kit is not very expensive

For the GM guys, these are probably more sorted out. I got one for my other brand of car that im about to throw in the middle of the track. I know its just getting it sorted out ............. but ....... Learning curve, BIG.

Well, I took "Not-for-Nuthin" out for a "ride" yesterday. Sometimes, ignorance is bliss and sometimes it's just a cover for stupidity but I did have a fun day and learned a few things. I'll post an update and (maybe) some pics later.

Back to the "Further Adventures of Not-for-Nuthin" or "You Can Be a Total Slacker and Still Go Stock Eliminator Racing".
For this chapter, I have added a set of 19.5x7" Hoosier slicks, the previously mentioned 22" Hoosier frontrunners/rearrunners and, after draining out the gas tank, some NHRA approved Sunoco 260 GTX fuel (98 octane, unleaded). That's all.
Did I mention anything about ignorance and/or stupidity?
First pass, I got the car good and hot and, still running the car in D3, went a 15.83 at only 82 MPH. The car is shutting off just past the 1000 ft. clock.
OK, I ignorantly/stupidly think, I'm getting into a rev limiter.
Second pass, I leave the line in D3 and after the car gets to 6000 RPM in 3rd gear, I shift into D4. And the car goes a 15.75 but does exactly the same thing at exactly the same spot on the track.Hmmmm.
Third pass, I cool the car down and make the run with the shifter in D4 BUT this time, I'm going to watch the speedometer instead of the tach. It goes a 15.655 at 82.75 MPH with the speedo indicating 105 MPH (remember, the really short slicks).
I am now running into the SPEED limiter in the ECU.
So, I'll finish this chapter by saying that I apparently need to kidnap a kid and download a program before I can go play with this thing again. BUT it did run within .05 of the index (DA 1940 ft.) shutting itself off at 1100ft and I still haven't done anything but remove the P/S pump that involved getting dirty.
I'll try and post a couple of pictures later.

I saw this car in action, Sat. 10-24-2020, at Cecil County. I like the little donut slicks on the front. LOL! Actually not a bad little car. Go Ecotech!

Probably more than one limiter in that computer. I don't think you can crack into it easily. We had Ed Wright exorcise a bunch of stuff for us on the Monte. Probably didn't want to hear that.

What about using an aftermarket computer? Is it hard to put in everything you need?

I just pulled up a HP Tuners file for that engine combination and body. the speed limiter is active at 106 MPH and turns back on at 104.

very basic ECU and should be very easy for you to come up to speed.

Most notable the Torque table limits in 4 gear. There are no COT or Cat Over Temp in this ECU.
Your rev limiter as 6500.
Could be a little in the shift scheduling also.
I have my own chassis dyno that I do some work on the side so I play with some of the late model flash ware like the HP Tuners.
Great project! Good luck.

Marty, You've got to re-read the title of this thread . LOL

Billy, That gas is kinda expensive for this program , isn't it?
Do you use it in anything else ? How much , per ?
