Oh My God! I was completelly confused about this!! I came to a conclusion that instead of 4 single byte values they were two 2byte values with each byte swaped...
Hey everyone my name is Rome, I am very new to Burning chips for my car but looking forward to learning how to get it done. I own a 91 GVR4 with the fallowing...
I am looking at the 1g stock fuel map graph in the files section. The excel worksheet includes values for both stock and modded fuel maps. What is the modded...
ur best bet is going to be to use e931(5speed, turbo) bin and xdf because u are not going to be able to find the changes for the gvr4 ecu. from the files for...
modded map is for extended timing and fuel coding that will read 3212hz and stock reads 1600hz or about15-16psi. some people use it and like it. i dont, i just...
The E931 xdf should work fine on an E943 GVR4 EPROM. The addresses are all at the same locations. The E943 xdf's out there are just an E931 xdf that people...
Code like that is not something you can change with an xdf file, at least not that I've ever been able to figure out. Tunerpro is great for changing...
Hello all, this is my first post here. Before I start with my newbie questions, I want to thank everyone for all the work that has gone in to all of this. You...
... for ... of ... Looks good so far! don't forget to load the actual timing and air/fuel maps in as well. I personally find the car more difficult to tune...
So, I've been playin with it some and I have another question. How do I change the load values in Tunerpro from reading "low,3,5,7,9,11" to reading the g/rev? ...
Jeff, Your presence on this forum is invaulable. I too would like to code a shift light on the E931 chip. If the code below works with your correction, where...
At stock location 676A you will find "03 2F 08", which is the statement to turn the CEL OFF. If you substitute the instruction: BD CF 90 that will tell the...
I have been working on this for a while now in my free time and just need to ask for some help. ECU: 1.8 NA US code Pertinent Changes: 210cc to 450cc injectors...
... Plug the O2 sensor back in. The code is written assuming it is functional. When it isn't, the code runs everything real fat and stupid for safety. There...
... Without having the code disassembled yet, I could not think of another way to keep fuel trims from being used. I am looking to test what the fuel maps are...
I think what I can't understand is why the AFR's aren't correct if you have actually found the proper Global Fuel location to change for the injectors? If you...
This is with the EB13 code. I ran the car for a few weeks with just the 450cc injectors (without the injector resistor pack) and it needed a higher Global Fuel...
But what base fuel pressure are you running? Did you swap in a 1G 5- speed FPR to change it to 36.3 psi? Jeff O. ... (without ... value ... in ... WOT ... his ...
Oh, sorry Jeff. They run 41psi base fuel pressure and we have not changed that on either car. Mitch ... Fuel ... were ... up ... and ... the ... for...
Then I think you should use 46 instead of 4A for the Global Fuel. That extra few psi of fuel pressure is ~6% more fuel that you aren't compensating for. Jeff...
Also, you should post the EB13 in the "Files > Other Code Images (firmware)" so we can all take a look at the locations you are changing, to double-check them....
... Good idea, it's been awhile but I seem to remember some NA code using different units for the deadtime parameter rather than the 24uS the turbo code uses....
For security reasons only a few people can save to the Files section. Jeff should be able to put it out there if he wants. The problem is that anybody that...
Ok, I will give that a test tonight. Thoughts on the "stock" car map scaling? Initially we were seeing A/F in the 11's where the original code was 13.34....
To me it looks like the target AFR's in openloop at ~12:1, so you aren't that far off. I think you should simply change the Global Fuel for now and see what...
I think your deadtime address is wrong. It looks to me, on a quick check, that its actually F379. But, as Steve said, those values look about double what I...
