Who's tuned big injectors using a Versafueler?

[SinisterX]

put a set of 160's in my mach1 as I was going to E85 soon. I filled in the injector slopes for the 160's but initial fire up it poured enough fuel to come out the DP's.


Has anyone else tuned the low imp injectors w/ SCT ? What else needs to be done to the tune ?

80's is as big as I've gone. When I first started with them the car would start then die. I pulled the plugs to find them dripping with fuel. I had to pull 20% fuel IIRC just to get it to idle. And I still had to work on the transfer from there.

Did you do all of the values or just the slopes?

 

[SinisterX]

I had 80's in it and that was as simple as entering the values.

noid light shows #8 constantly dumping fuel , idk why that is

I know numerous people have done this conversion !

Sounds like something isn't hooked up right. And it sounds like you found your reason for all the fuel being dumped in.

just an update for anyone who was curious

The injector wasn't working b/c the Versafueler had a issue. They fixed it no problem and now the car runs like a top, it was not so hot on 93 but perfect on E85.
Slopes we used were Bosch's which are not so hot
runs just like the high Z 60's,72's and 80's I had previously .

Only minor issue is a slight miss at about 200 MAF counts when you just crack the throttle to maintain speed.

Car made 750 hp at 7500 rpms w/ 13-14 psi at only 16* of timing on a Mustang dyno.

Big thanks to RTR Automotive in Palmyra NY for the help

Big boost next Spring after the big pump

Glad you got it worked out. Look at the LWFM table for the miss. I had some issues under 2000rpm at part throttle and the table helped a lot.

Glad you figured it out!
My Versafueler and 120# Lucas injectors run great together!
