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...
In a reply to your message at the bottom jeff, what is involved in remapping the addresses? I am running an E952 chip, would still like to log the fueltrims so...
You are correct Jeff. The fuel maps and injector size indicate a non- turbo. Sorry to bring up an older thread. Does anyone happen to have the stock Lancer...
... Dragging this thread back from the dead one more time. I'm in the middle of preparing corrections for 560cc injectors. According to Jeff and Steve's...
Stephen, Look again at what you wrote below. The quote from me agrees 100% with your calculations, except I evidently forgot to list the final (7th) value,...
Remapping is very easy. You just go to the logging address table and make the changes to it you want. BUT, the big problem is that I've never seen anyone post...
I am not sure if this is allowed, so if it is not please feel free to remove it. I have an almost unused Ostrich that my friend and I were going to use to tune...
Hi I've tried searching but I haven't been able to find a conclusive answer. OPcode CF is listed as STOP (2 bytes, 2cycles) in the 68HC11 instruction set....
Hi Jeff Example below. I should have said that this is a 6211 processor, maybe its a little different. The opcode has only come up in a couple of places so...
Cheers Jeff, I have had a look over a disassembly of the E952 but I am not sure its done correctly. The logging map I have doesn't look right at all compared...
Looking for some troubleshooting suggestions: My 91 GVR4 regularly trips error codes for the MAF (baro, airflow, temp) and the knock sensor. This is what I've...
If the knock sensor isn't grounded you'll get solid 9's for knock sum. I'd make sure the sensor is physically grounded well to the block, i.e. threads in block...
The only thing all those have in common is the sensors ground from pin #24. You might want to check the 15 ohm blue resistor on the ECU board, and run a...
Erik, I use this one from the EVO code: 83 83 84 84 84 83 83 83 80 80 80 80 80 80 80 80 80 80 7F 7F 7D 7D 7D 7D 7D 7D 80 7E 7E 7C 7C 7C 7C 7C 7C 80 Jeff O. ......
Anyone tried this out yet? I talked to Mark (TunerPro creator), and he said that in the next version of TunerPro, this will be incorperated into it. It will...
... Am i to understand mark has figured out the communication protocol with to read data off the odb1 for our cars? If so this would be a major breakthrough,...
Chris, You can change the baud rate by hand editing it in the ads file. Just open it with notepad. ... tried ... SMTPSVC(6.0.3790.2668); Wed, ... NNFMP; 09...
Hi guys, i would like to set the correct base timing advance but i don't know how to do it correctly. I know that pre 97 cars have a wire on the firewall that...
I bought a programmer a while ago but I have got out of this for the most part and I figured someone could put this to good use. I used the programmer once and...
I finally took a look at this, and I think you may be barking up the wrong tree. The E952 code appears to use the same addresses, L0x40, L0x41, and L0x42, as...
