Update: Tuning is still not complete. The car doesn’t want to start, it takes 3-5 tries in a row of cranking then it starts. I asked Uwe about this, he asked if I changed fuel...I did. I went from E30 to E40...so that’s not it. He recommended raising crank fuel pressure. It worked now it starts right up.
I have one fast street pass on Brads tune but it stopped pulling after 100mph. That was before the newest revision where crank fuel pressure has been increased. So now it starts right up no problem. Brads consensus was he shouldn’t have to add crank fuel pressure. So there’s a concern about low rpm/throttle fuel delivery. He said some ppl say large injectors aren’t streetable bc of the low rpm/part throttle areas. So far that is not confirmed as the case but now we will check that out more. I’m seeing a dip in fuel pressure on initial WOT. I’ve seen it range from 1200-1700. Now I didn’t see any rail pressure dips with the stock injectors and XDI35/DW300C. He’s explained for one on the 10-12 some aspects of tuning are limited with the HPFP. And more rail pressure is a way to extend the OEM injectors as far as getting the Peformance you need...but with such large injectors, at minimal pressure they’re still flowing twice as much so a drop in pressure isn’t really a big deal...although it is less than ideal.
I tried to do a log last night for Ortiz but throttle cut to 18% at the same time torque source 15 came on. I had trouble starting the car with Brad and Ortiz, and rail pressure dips with both although Ortiz rail pressure looked better. Both have raised crank fuel pressure.
So I’m still trying to make an attempt on the street. I won’t be happy until the car is running great and pulls all the way through ....then it will be whatever it will be. 10 or not it’ll be the fastest street Dragy....actually the pull I already did with it not pulling after 100 already is the fastest street dragy but I’m waiting to reveal the tests once I can feel that it’s 100%.
I’ve got big plans for the SHO, it’s now paid off and I’m about to pull the motor. I just want to get tuning of the new fuel upgrades sorted and tested first, then I will pull the motor. Only to find..maybe it’s already built lmfao!!!!!!!!
I am very pleased to announce that I am now sponsored by Xtreme-DI! Uwe Ostmann and I worked out a deal but there’s one catch...I go back to the track now....this Saturday and attempt to break into the elusive 10 second quarter mile time!!
