Do you have a good working knowledge of how engines operate and how they are controlled by ecu's?
Do you have access to a rolling road?
When either answer is No, stay away from it, as you will undoubtedly blow a couple of engines or turbo's.

yes i have a dyno ( rolling road ) and my mate is a engine builder and he would tell me what need tweeking if ya got me ill just me the man with the contols .....

im looking to find out whats the best and easyer software to use

can ya help

thanks

No, I do it the old-fashioned way. I decompile the software and then change it and compile it again.

**Wideon** · 20th November, 2009, 06:11 PM

is that possible to do this way and if so is that the best way to do it

please explane

thanks

You would have to be a experienced Software Engineer who has no problem understanding Assembly language an who would not be afraid to invest a lot of hours into the process.

well, you can at least share general info about your work and what advantages you have over the other programs in the market, then we can talk money

**oldford** · 20th November, 2009, 10:48 PM

The advantages are that I can correct bugs in the software or design. I can take out parts of the software and replace them and I can enlarge maps.
Two examples (both from 15-20 years ago):
a) Ford Sierra Cosworth (rear wheel drive)
There were a couple of bugs in the program, one of them caused the engine to idle at 3000 rpm, not a big problem but annoying. The other problem is more serious. Because of a bug in the program the ignition advance could be more than 60 degrees at 3000 rpm and full boost. This bug didn't show up in the standard car, because the conditions under which it occurred were not reached. When you tried to increase the turbo boost the conditions were reached. I repaired both bugs. The company that was the first to sell chips for this car didn't know there was a bug. There name was Detection Techniques. It soon became Destruction Techniques.

b) Renault Clio
People were racing this car with the standard ecu and were using rpm limiters at 7800 rpm. The engine was almost standard, so the power drop above 6500 rpm was considerably. The standard fuel map only had 12 (or 13) rpm entries and was insufficient in width. The engine would run correctly at low revs or at high revs but not both on the same Eprom. Tuners were using different Eproms for different circuits. So, I enlarged the fuel map from 12x16 to 20x16 and was able to get one Eprom that would cover both low and high revs. The result was that the driver, who would normally finish between 15th and 20th, in the next race finished 6th.

great work

, do you work with opel cars?? im asking cause this is my field of work that im intrested in

**oldford** · 21st November, 2009, 10:19 AM

I have nothing of the shelf for Opel/Vauxhall. All Opels I did had tuned engines for rallys.

**busaman** · 21st November, 2009, 10:30 AM

ive looked at winols and gave up far to complicated. i race bikes and use standalone ecus (motec) that actually have boost,fuel, and ignition maps.

not ones you have to search for and then unless you are very familiar with winols you neve know what map you are altering.

**oldford** · 21st November, 2009, 11:24 AM

I agree Busaman. After-market ecu's are a lot easier to setup. But they do have a disadvantage and that is the costs. You have to buy a ecu and have a wiring loom made. Acceptable for rally and racing cars, but not for normal road cars.

is there an easier software than winols for locating and editing maps.
