How Long to Tune EFI with Rob Sabbadin | Fuel Injection

One of the most common questions I get asked regarding tuning is, "How long does my car have to be there for?" 

Usually, I'll always recommend to a customer that we'll need the car for a minimum of 3 days, and to a maximum of 5 days.

 

Tuning is not just dyno time, where we go through the basic RPM of the car, load points of the car and into the power side of it.  There's a lot more to it, being how it idles, from high revs back to low revs, does it stall, cold starts.  There is nothing worse than a car that you start cold, and you've got to keep restarting it because it stalls.  All of this is part of the tune, and must be spot on - which isn't a 1 day process.

 

We don't like any of the cars leaving the workshop unless we know our customer is not going to get stranded somewhere down the road, or in a week somewhere because the car won't start because it's a different temperature to what it was when it was tuned, or a different condition.  

 

So, we try to put the car through all of the different conditions that we think it will go through.  Along with that, we usually try to take it on a drive on a road where there is various different scenarios, being traffic, being highway driving, being freeways, stop-start.  

 

Then, once we are happy with that, we are happy to give the car back to the customer.
