I have GIAC 91 pump program and I want REVO. Can they just overwrite the GIAC with the REVO or do I need to have the GIAC removed first at a GIAC dealer?

 

when you send it out to revo they will just remove whatever giac did to the ECU.

but why would you want to do that? they are very similar programs, there isnt really reason to spend the money unless you are upgrading hardware or something.

 

yeah man, stay with giac

 

Well first off I have a k04 and GIAC doesnt make a k04 file for my year car, they do 1999 and 2001 but not 2000 its weird andways yeah there is that and some guy hooked up a laptop with revo software and messed with my timing and stuff so I dont think its running right. So I want to go REVO stage 2 so its software that will be untouched and maybe do a little more for my k04.

 

im 80% sure giac makes software for your car with a k04, but its possible they dont. have you talked with giac directly? give them a call.

also dont let 'some guy' mess with your settings. that program was probably lemmiwinks which is made by revo. you can do a lot of damage if you dont know how to use it, but it isnt specifically for cars with revo software. revo sucks for B5's anyways. giac has the most aggressive software for a K04.

you can try calling giac and telling them someone screwed with your car and ask them what the default settings in lemmiwinks should be and they might be able to help you get back to what it was. unfortunately with that program, once you change something its instant and there is no undo button. so if you dont know what settings 'some guy' changed and by how much, its hard to undo them.

you can look in vagcom and look at your timing and fuel trims and try to do some tuning yourself to get the car running correctly. you shouldnt be pulling more then a few (4 or less) degrees of timing, so if vagcom says you are, then back off a little in lemmiwinks. if your fuel trims are way out of wack, slowly try to raise or lower the values in lemi.

 

If GIAC just flashed your ECU, there should be no problem with flashing any new chip. If they actually soldered a chip to your ECU, Revo might charge extra to remove it.

 

I did not just get my car GIAC flashed, it has been that way for almost 2 years. GIAC DOES NOT make a k04 file for my car so all I can run is standard 91 pump program. If REVO stage 2 is better than GIAC pump 91 then I am getting it re-flashed, if not then I will have it re-flashed to 91 pump GIAC. I was under the impression that REVO stage 2 would cater to my k04 a little better.
