The car before the 35r, was custom tuned by Big Al... Dynoflash.

Ok thanks I will keep and eye on the logs and watch the #'s.

 

I don't doubt that you go up to 300, but there are only 18 load bins, IIRC. Either way, sounds like Al rescaled you to 300 which will be sufficient on pump at least. Good job getting it all nailed down

 

The 9s have more load columns than the 8s.

Beat me to it...think they are scaled to 300 stock too.

 

lol, I thought about that about 5 minutes after I posted For some reason I thought he drove an 05.

 

either way thank you very much for your guys help

if i need to go higher i will down the road when i do a c16 map.

really quick when i do a c16 map.... i will just rescale the high octane map and leave low the same right?

 

No, when you rescale the load axis in just one of your AFR or timing maps it will change the axis everywhere(the fuel and timing maps in both high and low octane.)

 

so how do you do a dual stage map.

one for pump and the other for race fuel...or can you

 

You basically tune the high load ranges you'd only hit with high boost and race fuel for those conditions. Its not a good way to do it and I don't recommend it. You are much better off with individual pump and race gas maps. Changing the load scaling won't change anything though except give you a bit more headroom....its not a "race gas map" change.

 

OK I got you.

IF I wanted to, I COULD raise the table higher... say over 300. Buy doing so that "could" be the race gas map area. So as long as I keep it say under 300, 23 psi, that would be my pump gas tune, if it goes over 300 say 320's with 25 psi give or take a few in the load table, thats when everything would change... more timing and less fuel?

But what you are saying you would do is build another map for C16, and just reflash it for the race fuel map when I use it?

 

You could do it that way but if you ever hit those load columns for whatever reason on lower octane you can kiss your motor buh bye.

 

Yep. This is why quite a few people are hoping that the gurus can figure out a way to switch maps in the ECU on the fly. Then you could just have both of them in there and switch depending on gas.

Until then, this is a much safer way .

 

Live map switching has already been figured out. Tephra has it working right now.

If you only have race gas values above say 300 load the car is going to be a mess as you traverse your way to the higher loads (spoolup)

I suggest creating at second ROM for race gas and load it as needed.

 

Thats awsome!

Well I am going to Buschurs next week, and I'll do a whole new map for the c16 on the dyno when I am there, till the flipping of a switch for maps is done
