and a bin would be great! Its for a 94 suburban 350, TBI, 4L60-E tranny. A friend of mine wants to get rid of the 99 mph speed limiter in it.

I searched the diy-efi.org FTP site and came up empty.

Thanks

Isn't that a PCM? Do you have software and cable to re-flash it? If not, you may want to check out TunerCat. TunerCat's $0D TDF has a ton of things you can change besides the speed limiter. You can even do changes to the transmission.

 

Ya know Glenn I didn't even think about that..

Thanks man You've helped me more than enough over the years and certantly do appericate it

Location 4961 in the eprom is the speed limiter and it's a simple convert from hex to decimal and that's your mph. It's an 8-bit value, the resume speed is at location 4962. Just make sure that's lower than what's in 4961 or you'll hit the limiter and coast to a stop.
The engine speed limiter is at location 495D and I believe that is in value * 25 = RPM, it should be 8 bit as well. I don't know where the resume rpm is but I'll put money on it being 495E, just a shot in the dark though.
I'd still just get the TDF file from Tunercat, it's got a LOT of things you can do with the trans shifting which makes it extra "wow."

this i spotted a while back.

 

I have a $0D in my 95 sonoma 2.2L 4. If I were you I would upload the tables out of the prog that is in your sub and purchase the tunercat def file to mod it.
