Before I Get To the Dyno, What Should I Check On My Car?

Written by wolfems on September 10, 2009 – 9:59 am

Hi Everyone.

Sometimes a car arrives for a dyno tune. A pre-dyno check is done, all looks good. You put the car on the dyno, you run it up, it makes good power. A couple of tweaks are done on the test drive, a couple of cold starts, and the car is ready to go. That happens….. Sometimes.

What also happens sometimes, is the car is dropped off, there is less than 1/8 of a tank of fuel in it. You put fuel in it. You do a pre-dyno check and find a couple of wires that are not terminated properly. You fix the wiring. You put it on the dyno, run it up the first time, and an intercooler pipe blows off.

You take it off the dyno, spend an hour going over the whole engine bay to make sure nothing is lose, or leaking, etc.
You finally put it back on the dyno, and the rest of the tune goes according to plan.

But it’s been a bit of an ordeal, and the tuner has been under extra time pressures, and you probably have to pay something extra for the extra time spent.

———————————————————————–

So here is what you can do BEFORE taking your car with programmable electronic fuel injection to be dyno tuned.

1. Make sure you have at least 1/2 a tank of fuel.

2. Go over the engine bay – wiggle and pull on wires (not too hard) and connectors, tighten (not overtighten) all fuel lines, hose clamps, brackets.

3. Make sure your tires are inflated to correct pressure and that your wheel nuts are tightened correctly.

4. Write a list – of anything that you are unsure about. There may be a slight oil leak, or something may have been rubbing on a bracket, there may be a vibration you noticed but you are not sure where it is coming from. Anything like this should be written down.

5. Communicate your list to the dyno tuner. They need to know anything that may cause delays and add costs to your tune. You want to know this up front, as you don’t want a surprise half way through the tune, or at the end getting handed an extra bill.

There you go. If you follow these 5 basic steps, you are very likely to have a smoother dyno tuning session than if you don’t do any of the items in the list above.

That’s it for this one.

Until next time.
