Thorin Posted January 12, 2003 Share Posted January 12, 2003 I'd be interested to know from some of the more knowledgable peeps on the board (Chris Wilson?) if there would be any problems with running either of these fuels on stock ECU? Link to comment Share on other sites More sharing options...
Alex Posted January 12, 2003 Share Posted January 12, 2003 Due to the fact this fuel is unleaded it should be ok. I asked them if it would be ok on my non-mappable ECU. And they said it should be fine. Obviously they have not worked on one of our cars before. But they did say the RFT is the best for turbo/forced induction. Probably due to the O2 content. The EGT's might need to be watched but it should really wake up the J-specs especially the ones like mine with a MINES ECU. But I would like to hear CW's thoughts.....

Adam W Posted January 12, 2003 Share Posted January 12, 2003 You'd be able to run a whole load more spark advance on boost, reset the ECU after filling up and you should feel a mighty difference! I guess if you were running really high boosdt on a big turbo it ould enable you to run a couple more psi without detting also, but that's probably not a concern for most of us.

Thorin Posted January 12, 2003 Share Posted January 12, 2003 Tempted to buy some and try it out but if the RFT wouldn't offer that much more of an improvement with a stock ECU over the other stuff then I'd rather save my money! Link to comment Share on other sites More sharing options...
SMW Posted January 12, 2003 Share Posted January 12, 2003 You'd be able to run a whole load more spark advance on boost, reset the ECU after filling up and you should feel a mighty difference! I've read before about resetting the ECU in order for it to self adjust if you use something like race fuel. Just wondering how long you'd need to run the new stuff in the car before the ECU completed this "learning" process, or can it do it pretty much instantly?

Just wondering how long you'd need to run the new stuff in the car before the ECU completed this "learning" process, or can it do it pretty much instantly? Fill it up. Reset. Warm up. Couple of WOT blasts. Idle again. Job done. The ECU will adjust the timing and listen for knock. If it doesn't detect any than it'll run very sweetly! I'd love to test some hence I got the quote. Bit too rich for me - but hopefully someone else can run a test. Terry S, was this what you ran for you race fuel? Link to comment Share on other sites More sharing options...
Thorin Posted January 12, 2003 Share Posted January 12, 2003 Cheaper fuel here! http://www.gulfracefuels.com/HiperfloCF500/index.html You can collect from Rockingham speedway so might be of interest to people going there in march. Link to comment Share on other sites More sharing options...
Alex Posted January 12, 2003 Share Posted January 12, 2003 I looked for a Gulf Fuels web site but bizarrly no search engine brought that one up.....should have guessed the address DOH! Looks like the exact same fuel. 76 say theirs is developed by A fuel co. not themselves so this may be it.

Guest Terry S Posted January 13, 2003 Share Posted January 13, 2003 Yeah I have a map done on the 76 stuff, the 100 MON unleaded. We conservatively mapped to 25psi, but I would think Paul could run his 30 psi on it OK. Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 13, 2003 Author Share Posted January 13, 2003 So whats that 106ron approx? I'm getting interested now....might be a good idea for drag racing and the odd dyno shoot out... Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 13, 2003 Share Posted January 13, 2003 100 MON! Link to comment Share on other sites More sharing options...

You rekon there could be about 10 degrees advance set for that kinda fuel? (with appropriate ignition, air, fuel setups ) Gaz. Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 13, 2003 Share Posted January 13, 2003 Gaz I dunno about that mate, it really depends on sooo much. We made more power on it yes, but I had it mapped with this purely as a safety measure incase I wanna do track days etc. I won't run it on the street as it would get too expensive. No one can tell you how much more advance you can run until the engines tentatively mapped & on a dyno then add a degree at a time. Link to comment Share on other sites More sharing options...

I think its works out circa £2 a litre or something like that I heard. I'd only run it for dynos, drag & track use, just as you say, expensive stuff. However, with the AEM can just swap the maps quickly between optimax and race fuel and away you go once alter the timing! Gaz. Link to comment Share on other sites More sharing options...

With the Autronic you can swap maps even quicker:p Link to comment Share on other sites More sharing options...
