Last year I had my car tuned by the man everyone is Sydney considers the best.
Well the engine died for a number of reasons but it showed bad bore wash form too much fuel and the mains were suffering from running in a strong fuel/oil mix.
Today I dropped the car off to be dyno'd by the shop where I assembled the new engine.
They've never worked with an Autronic system but got in and had a look to see what was going on.
When they plugged into my Autronic the engine was running an AFR of 10:1.
The first thing they did was drop the fuel load by 50% up to 2,000rpm and it settled into a nice smooth 1234rpm idle and it smelled much less rich. We'll get the idle down further but this was just a learning thing. We didn't go past 2,000rpm today as there are other cars to be tuned before mine.
The ECU told me my temp guage is 20 degreesC out. When the gauge shows 100 degrees the ECU is saying 81 degrees. I won't stress so much now when the temp creeps up to 100 degrees.
I also found I was running intake temps of 62 degreesC where last year is was way over 140 degrees. I put this down to the new W2A intercooler I installed.
An interesting side light was I told one of the shop employees of the effectiveness of the intercooler and he held his hand on the pipe from the cooler to the manifold and he was impressed. He then placed his hand (palm down) on the hot side pipe of the intercooler and removed it very quickly, but not quite quick enough. Nice burn.
This experience fly's in the face of all the advice we all give of finding someone who is good with your ECU and using them.
Hope to have the car back next week and I'll post up some figures. I'm doing this run with very aggressive and heavy 35" mud tyres on it so I don't expect any earth shattering figures.
