For those experienced tuners, how do you account for Heat Soak when tuning on a Dyno? From what I've read to tune for ign. you keep advancing timing until no further power is gained and then probably back timing off by 1 deg to try to get some longevity out of the motor.

That all makes sense to me, but tuning a JRSC... heat soak WILL be a BIG problem as the last time I was dyno tuning with a LINK ECU I had heat soak and had to let it sit for 15 minutes under the fans since I kept losing power with each run. Its there any tricks any of you use to tune accounting for heat soak or is the only alternative to wait and let the manifold cool off? Although that seems simple enough to wait to cool off I'm sure we all know we pay by the hour on the dyno.

 

I always let the car cool off between a few runs. Pop the door open and let it get cool air. That is the only way to do it or IATs go sky high, where I dyno.. they can't have the doors open for cool air to pass through.
