Fooling my ECU chip with WI
I have an after market chip On my 02 GTI 1.8T with three programs ? Stock, 93 Octane and 100 octane program. The 93 octane program raises the boost level and advances the timing from the stock level. The 100 octane program advances the timing to a more aggressive level but 100 octane fuel must be used other wise there is a risk of losing the engine. I understand that water injection makes it safe to take your boost and timing to a higher level therefore and in my case switching to the 100 octane program with 93-95 octane fuel + WI can more or less give the same performance as running 100 octane fuel?
