good source for pure toluene?

[David]

I can chime in on this one. I used toluene in my Passat 1.8T. I beta tested some chips for Rene Berube (president of UPsolute USA) when they first began chipping the 1.8T in the USA. I had a 1.2 bar chip (or 2.2 bar including 1 bar atmosphere) in it for about a month. It would detonate on 93 octane gas so I had to up the octane with toluene. One gallon per tank (roughly 12 gallson of gas + 1 gallon of toluene) completely elimated the detonation and allowed the ECU to use the more advanced timing maps. It made a big difference in the feel of the engine. But it was a VERY expensive way to go. It makde a normally $18 tank of gas really cost $27. That was jsut too expensive to run in the long term, so I swapped the chip for a 1 bar chip...

My opinion is that like anything else it won't be perfect the first time around, and it takes some refinement (of the experiment conditions) to find the best results.
