If you upload your rom then I may be able to help you as I have also been working on E952 roms cheers Brian ... cutting ... like ... software ... limit... ... ...
How do I input a tps controled activation into the existing code? How do I figure out the hex corections for say 50% and so on? This is actually for a...
The TPS and RPM values should all be covered extensively in Christian's disassembly. The TPS is address D2 and is scaled 0-255 for 0 to 100%. So, 50% is 128...
So, you mean 5200 address then? And then how would I do these load and compares? I am new to this. I know I need to do a look up and compare code but am not...
Its a little beyond the scope of this Group to train you to write code. Do what I did: go to Books-a-million and buy a good 68HC11 code book, and study the...
Alex, That section of code does an "octane reset" everytime the ECU is completely rebooted, by reloading "FF" into the octane value, setting it to full octane....
Sorry to bother the group with this, but I think this is the best place to get this answered. We all know that EPROM ECUs have the "E" on the front label....
Ive fixed the issue, it was a wire...I am still interested in changing some of the code on this chip. id like to lower the rev limiter upon normal driving...id...
Andrew, I thought I told you how to lower the rev limit? The one way you could do it is by simply changing BD C550 back to 8C 01F4, but that would also...
Hi Mitch, I don't have an answer to your letter questions, but I could change the description. I'm surprised that it allowed you to upload it, but then won't...
After finally solving most of my tuning issues by ditching my MAFT (thanks ramcharger) for a 2G MAF and a very modified MAF comp curve, I gave lean-burn a...
Well my first attempt to write some code failed...lol. I have an led hooked to the purge solenoid wires, and it is lit constantly. Can someone see what i did...
Tom, Just a couple preliminary observations: 1) the coolant temperature address is CB, not 07 2) 210* F corresponds to ~98.7* C, which, according to...
I don't see how that can be related. The code you are modifying only affects the Purge Solenoid. Jeff O. dsmchips.com ... Christian's ... an ... Can...
I'm sorry if this is too much of a new guy question, but I searched and I can't find out what I'm doing wrong. I have a hongkong Willem burner and I haven't...
So what would be a ideal chip to use that is electronicly erasable? Is this a common error for a chip that is still written on, or written with FF for the...
Many thanks to Ibartik for finding the piece of code which limits A/F ratio according to TPS and relating it's effects on lean burn code. I changed the TPS...
Hi Guys Additional question: Can the E943 USDM Galant Vr4 program run on the MD165808 GVR4 ECU-Cyclone Manifold? What are the issues? Thanks in advance. Alvin...
Ok so i found this fourm recently. Let me give you a little background. I've been working in the GM ecu tuning field for about 3 years now. I was one of the...
Ok i had an idea for logging with moates gm aldl hardware. His hardware reads the data line and returns to the laptop the data values. Would it be possible...
i dont think it is an issue with the cable. i have gotten it to say connected once. i think the issue lies more within the baud rates differences. that and i...
I'm not sure if anyone even traffics my old site anymore, but if you have any weblinks to something I have leftover on tmo.com, please change them to...
