PFC map tuning HELP!!!
Hi . I've made a single turbo and PFC upgrade.
Does anybody have a map for me??? I live in Argentina and have no-one who can make a "fine" tune...
wanting to run at 15-17 psi... (hopefully)
Stock engine and fuel setup.
+ GT35R Single turbo upgrade.
+ V mount intercooler
+ Power FC with Commander.
+ 255 lph Walbro fuel pump upgrade
+ 6 puck ceramic clutch

I doubt few if any will recommend running 15-17psi with the GT35R on stock injectors. That should be in the 400rwhp range.
You could probably use Westbrook's or Kan's timing maps, make certain you have the same map sensor magnitude.
You should get a wideband and tune the fuel.

thanks books~!
What psi should be the best???
Can you, anybody tell me where to get Westbrook's or Kan's timing maps???
isnt there somebody running single turbo upgrade with stock fuel setup???

You would have to pay me $75 for a custom map and that would include tuning notes. This weekend is a holiday and I will be away from a computer until Monday.
If interested, PM me and I will reply when I return.

How much boost you run is somewhat dependent on how comfortable you are running high injector duty cycles.
You can use Max Cooper's website to calculate horsepower for a given set of injectors at a particular duty cycle per centage.
http://www.maxcooper.com/rx7/how-to/...tem/calcs.html
At 85% duty cycle Max's rwhp is 288.
Assuming you were at 400rwhp at 15psi, and assuming a 15 rwhp increase/decrease for each pound of boost, then
400-288= 112 hp 112hp/(15hp/psi) is roughly 7.5 psi so 15-7.5=7.5psi
These are calculated numbers and I am not certain if they take into consideration air temp or AFRs. You should also be aware that your injector duty cycle is not max at the same rpm as peak horsepower.
The following is values are from a dyno run on the stock fuel system; 321 rwhp 84% injector duty cycle, 6800 rpms.
I actually believe you could run around 10 psi with the 35r. Just keep an eye on the commander for your duty cycles. But of course these are risks you would be taking. You'd probably be better off just purchasing some 1200 or 1300c injectors, they are easily swapped out.
Or you could just have Chuck help you out, well worth the $75.
