Tuning the truck

[SRT10VENOMOUS]

Well getting the old girl sorted out slowly,

So we did some testing on her today, and found that shes running a lil messed up " which was suspected"

So bank one or left half of the motor running at 15.1 air fuel
Bank 2 or right half of the motor running at 11.1 air fuel

And 3rd cylinder not firing at all,

Fuel pressure drops to about 20 psi after boost gets above 10psi..


So that would explain the falling on its face down low and never really feeling like it should,

Sooo we have a few fixes coming this week and after we get our base line straight, we will go on from there and aim for some bigger numbers,

And when she was originally dynoed she came in at 715rwhp , come to find out running on 9 cyl and almost no fuel pressure " DOH"

ohwell no damage was done luckly that we can see at this point, soooo one step closer to getting this thing figured out and tx mile ready..

Will be nice to get this beast running the way it should have from the beginning...

So by next week we will have the new fuel system in " dual tank set up one race gas the other pump" and will be back on the 920rwhp range that was originally

achieved with this build.. And from there upward and onward ..

Oh and new trans coming that can hold power, not a auto and not a t60 or t6060..

who's tuning the truck or what software are you using

 

[viperhauler]

You doing a sequential manual or traditional manual?

 

[SRT10VENOMOUS]

AEM software and psi in Portland.

Wanted sequential but they are 25k for a good one.

But more of a dog box setup can use or not use the clutch.

Someone please explain to me how a well tuned vehicle becomes un-tuned? :dontknow:

apparently faulty fuel system, and some issues with cylinder #3 injector

A fuel pump goes out an injector quits working

You are lucky your mot building a motor

And who the fk doesn't watch there fuel pressure when they are making a pull????

I have alarms setup to shut my truck off if my fuel pressure drops

I have my fuel pressure gauge set also so the red light starts to flash under 50psi.:drool:, I like the shutting off idea better!!!

Sounds like you're making good progress Kenneth! October is a going to be one hell of a month!

Are you shipping the bike over as well ? for your old lady to run down the track?

 

[SRT10VENOMOUS]

Yeah the truck was put on the dyno for a quick pull when I got to PSI just to get a base line and that's the 700 pull, it got lean real quick and we got out of it, that's when the fuel dropped, so we did not run up to red line or anything, as soon as it dropped we got out of it.. it was in the 5k rpm range when we lost pressure.

And putting a kill into the AEM should be simple and a good idea gonna pass that along to them...

But playing with someone elses build and trying to figure it all out is tons of fun, all sorts of little things you dont expect to find..

Anyhow when its done it will be hopefully running in a way that im happy with and hopefully it can go fast at the tx mile, " hopefully at least 180/90 and if we get lucky maybe 200 but that might be a tough goal..

Bike is going straight to TX... she will be running it, then I'll send it Dubai. M5 will be good for 2 Mile events (maybe 3 depending when the date for October 2014 is) as I can import it for 1 year and drive it on the Dubai plates.
