Oh I know bud, I was telling someone else in this thread that the car is not spinning on the rollers that is definitely not the issue as the graph would not look like that.

Do you roll into the throttle or stab it?

i suggest to return to stock TCU and stock gear ratio.
if u have on the car another TCU, it will not connect clearly with the ECU, and u can verify this with star diag as the tcu will not take coding with the vin/model designation of the car.

Update fellas,

We are re-doing the fuel system now to return style. The fuel pressure is dropping during a pull and throwing misfire codes.

The current fuel system is:

1000cc injectors
dual 340lph Division X fuel pumps
modified stock fuel baskets to accept more fuel
brand new sender unit assembly
BIP looped rail with drilled out feed rail opening

The pressure is sitting right at 82psi at idle, and at the end of a pull where is starts to break up, it is 67psi. This is with seeing 13 pounds of boost.

Sorry to see you still having issues Craig, hope you get it all sorted out brotha

Can the injectors be too big?

chawkins2001

Changes that were made to the fuel system are as follows:

* Took out the factory sender unit, and removed the stock fuel filter.
* Removed the factory fuel pressure regulator below the sender unit.
* Ran a bigger feed line upfront to the fuel rail, and put in an inline fuel filter.
* Ran a return line back to the gas tank off the loop portion of the fuel rail, with another inline fuel filter.
* Installed an engine bay fuel pressure regulator.

The plan is to have the car strapped back down to the dyno by tomorrow morning. If the fuel pressure holds constant and does not drop, and the car still breaks up, then the kit will be pulled off and sent back to the vendor.

Yikes! Hope it works out for you Craig

Chawkins, is all that really needed? Did the vendor tell you to do those fuel mods? What about rbj claiming he didn't mod any fuel system and still having stock injectors? I really do hope you get it sorted out bud.

chawkins2001

Removed factory regulator and factory fuel filter.





Joncl, the vendor has not given us any feedback on what to do. I have done research along with BIP on our own, and tried to address all the problem areas. RBJ's kit and mine are different, so it is hard to compare why his runs and mine does not. I am not R&D'ing the kit anymore after this fuel pressure issue. It will be pulled off and sent back.

Joncl

Sorry bud, this is the vendors responsibility not yours.

Good luck buddy hope this solves it all

chawkins2001

Me too bro, one thing I know is that I will be running the car with some combo on there at wannagofast.

Worth the wait

Way to stick with it!
GOOD LUCK

If you can keep the temps down get a 3.0L blower or better yet just get the Biturbo from AMG what ever path you take I hope you have great results. must suck not driving youre car for over 4 months

and spending money left and right to get the thing working

I am using stock fuel system. The stock fuel injectors ran out at 11psi and 5800rpms. So we installed the Eurocharged 550 injectors and I'm at 14psi and holding to 6800rpms. Gonna go back to the track this week with 18" MTs and front Skinnies, full interior on 93oct. We are putting in a 3000 stall converter to see if I can get off the line faster. I'll post another thread soon with dyno pulls and other info. Sorry for the wait.

RedBullJnky

Craig, I hope you get this worked out. I would hate to see you send the kit back. You've put In a lot on this. Good luck brotha!

I don't understand how the vendor could be at fault. Could you clarify why you believe this?

Joncl

Don't know if that question was meant for me lol but I do think if you buy a product from a vendor and do everything as they say and then use 2 or 3 different tuners to get it to work and it does not work as advertised or agreed to, wouldn't they need to back up their product?

chawkins2001

all done!

Joncl

Looks super clean bud, good luck

Roverron

Good Luck...

Well then fire it up and report back with the all clear and get Tony to knock a tune out on the beast.

Looks like that fuel rail inlet is restrictive. Hope to hear some good news from you soon
