I am trying to understand what parameters need to be adjusted to gain control of the aux DW300 pump. I installed the dual DW300 kit with the updated higher pressure regulator. The fuel pressure...

I am observing a lean condition 1.5-2 seconds into PE. It is pretty dang consistent. Commanded PE values change between 2500-2700 rpms right after entering PE. I am going to try and kill prediction...

That advice DSteck provided in the above attached link fixed the issue. Trims in the lower KPA ranges were not too bad either. What do these VSS parameters do exactly and how does this influence the...

I'm also curious about this? I'm seeing values > 200 KPA in logs and wonder if this tables needs to be adjusted for any reason?

Awesome! Thanks I will give this a shot tonight after work and test. I imagine that I will need to correct < 40 KPA in VVE after correcting trims on decel. I have been filtering < 3% throttle so it...

I have dialed in my VVE to within +/- 3% up to 3,200 rpm. I still have a few spots in the -9% range around 15-20 kpa, but nothing richer than 13.20 AFR during deceleration in OL. Switch over to CL...

I have been playing around with this program for a couple days now and I have a few questions.

I have a VE table that I would like to convert to equations to enter into my E67 VE Equation...

I took a similar route but with modded ls2 42lb injectors flow matched. I used all the fuel data from a stock 07c6 file offset, min pulsewidth, pulsewidth adjustment, and adjusted my IFR table to...

It will work, and it has worked on dozens of other setups. The only difference between the stock injector and the modded injector is a slightly larger oirifice area.

I have talked to several...

I had the FAST 46lb injectors and I could never get them dialed in without having to do some severe scaling of my maf I am talking 10+ %.

What I did, and what several other people are doing with...

Problem should be solved I ordered a set of custom modified vette FIC ls2 42lb @ 58psi fuel injectors this morning. I will need a 0.20" spacer on my fuel rail mounts and thats it.

Load up a 07c6...

I know its not the same as if I had ls3/ls7 injectors, but if I can start with this setting and just make +10/+5/+2 % adjustments while logging results I bet I can get it to within +3% at idle. If I...

I have not tried the 07 zo6 voltage offset yet, but with the current improvements going from the 07c6 to the 08 c6 offset tables I bet it is going to improve that much more.

I have not messed...

I did some tweeking last night.

I have three logs to show.

All are using a basically stock MAF HI and LO transfer table with minimal changes. The first is using a 07c6 voltage offset table...

I just found out that Bosch makes the injectors for FAST so this is a good thing. There should be some published values on these style injectors then? The offsets must be way different than the stock...

So too properly tune this setup I am going to have to scale the IFR table then correct LTFT to within +/- 3% and then just run MAF only? Because that is currently what I am going to do.

these are supposed to be high impedence injectors or at least they are advertised that way. I didnt think that the stock computer could drive low impedence injectors I though you needed an injector...

Well I will just have to patiently wait for all this injector data to become available. Wow thanks to Greg Banish "eficalibrator"!!!! I hope he includes the values for the FAST ls2 style 46lb...

If scaling is wrong, then did I take the right approach by just coming up with a multiplying constant based on original IFR talbes then adjusting to the 46lb FAST injectors? I couldnt see any other...

I just did the injector rescaling in the IFR table flow rate vs. Press tab. I divided my 46lb/hr @ 58 psi by the factory setting @ 58 psi then used that factor and multiplied by the stock values and...

I have a max effort Heads, cam, TBSS. I have switched from the stock ls2 injectors to the FAST ls2 specific 46lb injectors rated @ 58 psi. This is an 07 with e67 computer.

Question 1:
In the...

Will do.....

thanks alot guys

I almost have this heads, cam, built tranny TBSS dialed in.

I have a wideband, but I lost the serial cable so I cant adjust the settings on the wideband to output 1v=20afr and 5v=10afr so I have just been looking at the wideband itself while going WOT to see...

How are yall logging to correct MAF tables? I am setting my dynamic airflow enable high to 0 (I guess you don’t want VE influencing the logs?), then logging my STFT and LTFT and then taking the...

Thanks for the response I will try this.

Thanks
