Fuel Injection How To: Often Forgotten Pre-Dyno Checks.
The checks that you should do before putting your car on the dyno, are pretty much the same checks and maintenance that you should do to your car on a regular basis.
Do you have anything around or near the exhaust; as the exhaust gets the hottest on the dyno. So, if you have wiring that is close to the exhaust system, there is a good chance that it is going to catch on fire, or melt.
So, you want to make sure that you have nothing hanging around near the exhaust pipe, whether it be material wrapped, or you might have rubber line that is in braid, you really don't want it anywhere near the exhaust.
Another thing to check are things like the condition of your engine's fan belts. Condition of radiator hoses. It might appear fine for you to think that you can run the car with that fan belt on the dyne, and replace it later, because at the moment, it's still spinning the pulleys.
But, once again, please remember, a dyno tuner is going to be getting the peak out of your engine, so, it's going to be pulled to a higher RPM. If that fan belt is in bad condition, for the sake of a $50 (or less) belt, it could come loose and take out a lot more in your engine bay while it is on the dyno.
Another thing to check, that a lot of people don't realise, is oil condition. If you haven't changed your oil in 15 or 20 thousand kilometres, it's going to be like slug. Don't put it on the dyne.
These were just a few examples of often forgotten pre-dyno checks.
