We had a great day here in Florida and I got some data. I will post the two logs and the tune file. It seems to run really well except when you let off of the throttle it goes pig rich. Then when you...

You are correct there is no return line or air connection, I just assumed that thing was thr fpr I guess you can tell that I'm not a mechanic! I'm dead broke right now and pending loss of employment...

The stock fuel system is bone stock, no hotwire mod yet. I thought the regulator was on the fuel rail on the F body. I have the light wired to the hot side of the pressure switch after the relay and...

I dont know the actual fuel pressure, the main fuel system is the stock in tank pump supplemented by a second pump connected directly to the fuel rail that is pressure referenced to kick in at a...

I forgot to attach it, so here it is

Here is the tune that I was using.

I did get a good run or two in today and the car is still not right yet. When you let off of the throttle it is going way too rich and when you first get back into the throttle it goes way lean to...

I set up the Ben map exactly like the tutorial said and use the filters before the cut and paste to the tune. I did get the map sensor reading the same now so I will try to get some good logs to do...

The MAP was off. The stock sensor reads 31 in hg and the 2 bar reads 29.2 in hg key on engine off. I don't know how to convert it so that it reads correctly.

I will rescale the map sensor to the old one, I was trying to avoid that but I guess it has to be done. I'm sure my wideband is dead on as I just did a new sensor and freeair calibration before I put...

Hello Johnv,

I tried your tune and the AFR was all over the place and the car did not run right at all. I gathered data and did the first autove swap (log 39) and it made it worse. I will post...

Ok the injectors are in and it seems to running fine except when you let off of the throttle it goes way too rich and it is really rich at idle. If someone could help me get it to a decent tune I...

Alright I have purchased the injectors and should have them installed this weekend.
I bought Siemens Deka "mototron" EV1 60lb/hr, now my question is what is the best way to set these up. After...

I have a 2008 Impala SS and it has DOD and I think it goes back to 2006 on the LS4 engine. I'm not too sure on the VVT

Here is quick run around the neighborhood with your tune, it runs really good but seems to idling a little high.

I did follow the tutorial to set up the map sensor, my boost gauge was only reading 3or 4 lbs of boost which I don't understand because it is set up for 6lbs and the headunit was just rebuilt less...

Thank You so much.... I get my bonus next weekend so I will be buying the Injectors soon after.
This car is actually fun to drive again!

Here is the latest log and tune file. The car seems to run extremely well right now and it is very cool out at 60 degrees.

I thought I did press the red button but I guess I just got so excited to actually get the car out again that I forgot to do it!
Thank you for the instruction on how to change the pid as I really...

Ok,
I got the MAP Sensor in and calibrated, threw a new set of plugs in (one range colder) and the car seems to running better then ever and I also took out the AIR system and the EGR system and...

Do you know what the stock size injectors are or what size do you recomend I get for it?

I think if I can find someone with small hands they can reach the map sensor, I will try to find someone...

I'm running the stock injectors, the boost is pressure referenced to kick in a second fuel pump which is working because I installed a light to come on when it is energized and when tested at the...

I have a 99 ls1 Camaro with a powerdyne 6psi kit. the car is bone stock except for a magnaflow cat back and a built 4l65e trans also meth injection set @3psi. I have been playing with this thing for...

the shifts feel much quicker but not too harsh

I have the stock 99 ls1 injectors and I have no idea what the IFR is.
Is it safe to up the pressures in a trans with a shift kit? I went 10% higher than stock and took the shift times down by 10% it...
