[Fot] My new tow car....

[MadMarx]

I was concerned if the Hummer H3  3.5L could tow my race car up steep hills
here in Europe.

As this car is made regular fuel I thought I could rise power and mileage
with some chip tuning.



So I bought an US software and created a new spark map.

Today was first test.with great result. Great torque, more top speed, and
it looks very promising for a better mileage.



I changed the ignition advance more to a racing style.



The stock total advance was 19 degree, now it has 29 degree which I dared
without a rolling road dyno test.



Next few days will show what consumption the car has with 98RON.



Cheers

Chris
