UPDATE: Hey guys, well just wanted to give an update.
I've abandoned the popular tuners in the ranger world. I'm just fed up with all the non-communication and unwilling-ness on thier part. So.. I bought a SCT pro-racer package
from Lasota racing and am tuning it myself.
I've learned a lot in the last week. Tuning is not easy and it takes MUCH trial and error. But once you get the hang of what controls what and what nomenclature means what.. it's not too awful bad. I must comment though that the descriptions they use are not straight forward. EE's
Daily driver tune:
I've been tweaking and tweaking and my DD tune is now getting ironed out. I'm making it so that when I give it light throttle inputs.. it shifts just a hair firmer then stock. And the more throttle I give it.. the firmer the shifts.
I'm just **** about taking small steps and making sure nothing goes "boom" so it's taking time. But trust me.. this is how Ford should have made it to begin with! Soft when you wanna take it easy. And a good jump fwd when you want to get with it. Oh and with these mail order tunes.. that annoying clunk when you lift off the throttle at 15-20mph? Yes indeed. It's tune related and can easily be soft.
WOT A/F can be what ever I want. Right now I'm running a downsloped 13.3 to a 12.7 on the top end. In my experience a little lean down low helps with off the line TQ.
Well I'm doing most of my tranny developement in the DD tune. So the tranny aspect is mostly the same except for WOT shift points and firmness.
When your making this much more power the tranny will slip more and the shift point will be higher. So I have to give it a bit more pressure and command the shifts a little sooner.
As far as A/F. So far I'm pushing a dry 50shot ramped up for 1.5 seconds. And I have no problem running a 12.0 ratio! This is good news because of two reasons. First, I was worried that the stock fuel system wouldn't keep up. But it's doing just fine. (btw I am commanding a 10.1 ratio and it's running 12.3 to 12.0) Second, no one had more than a guess at what the stock fuel system limit is. On my 06 I can push a 50 shot into the 11s w/o a problem.
I'll make a video and post it in this thread so you guys can see what I'm talking about.
I'll have to tweak my nitrous ramp time & size when I get to the track because of traction. On the street with a 1.5 second ramp... It's nice. I can mat the throttle from about 0 to 5 mph and the truck just goes fwd.. until the nitrous comes on about 50%. At that point they start to spin. If I stay in it they will spin for a good 30-40ft and then it just HAULS BUTT!
I'm confident it's running a high 14 as is. I'm sure it'll spank my caddy eldo w/275hp.
