After more research it becomes plain that this is a gen5, LT type throttle body. Older LS throttle body will not work with it. I’ll look for options now that I have a better understanding of what I...
I?m trying to find a way to connect a 90mm LS throttle body to replace my 87mm one for my 2017 6.0 truck. Both the 90 and 87 have 6 pin connections but the 87 is a flat connector and the 90 is in 2...
Ah yes, that was misleading. So many Corvettes at the track last week! Just had them on the mind is all.
Look at your spark timing, commanded small timing fluctuations at idle air masses can cause the fueling to move too.
I?m a little green with the new lifter theme. Is there a way to prelube the new lifters that you would recommend before installing? I?ve heard some say soak them in oil which will fill them, others...
I’m trying to understand the reason to keep O2s on a track only car and I don’t really see any advantages. Open loop seems to allow me easy control of fueling without having to learn the...
I’m putting in a 224/224 .600 .600 110 lsa. Also a 3200 rpm stall because low end will be gone if stock. I’m running 6L90 with 4.11s. I have the shifting for 1-2 at 5200 and 2-3 at 5400. The...
A lot of things change fueling as the car runs normally. Unless all those things are disabled you will see different fueling happening at different times. You can tune those things off or you can use...
After I dialed in my timing and MAF fueling my VE airflow was lower than MAF airflow by around 30 percent from 600 to 3800 rpm and from 3800 rpm up the VE AF was lower than the MAF AF by about 15...
After playing around with the scanner and learning what it could do I was able to pretty easily tune the VVE. First I dialed in my MAF tune, then I applyed a comparison of MAF vs VE on the bottom...
You can tune the deceleration areas in MAF and VVE tables to give you the amount of engine braking you want if you choose to turn off DFCO. I?ve been working with it and now have it how I like, not...
I run with DFCO off and open loop. Haven?t been having any problems and I?m very happy with the tune. Also I don?t allow my TCC to engage at all in any gear. I like the feeling of the simplicity of...
I recommend purchasing and installing a wide band sensor. It was what I did along with starting to tune my Silverado and it simplified things a lot.
The closed loop adjustments have to be monitored when setting up the Idle air. If Maf or Sd is way off then the ecu may throw the AFR way off trying to correct for that and the swing back can be...
Yep, just shut it off in the tune.
When I first started it was quite a jump for me getting used to the interface and the deal with coefficients on the VVE tables were like magical at first so I just tuned the MAF separately with the...
For myself it was not such a straight forward process as just maf, Vve, then spark. After reading basically all the threads I could on tuning my truck I came to the conclusion that there are many...
So it would seem that maybe some insulation around the wire and IAT sensor or maybe some kind of plumbed in fresh air dump on the sensor would solve the problem? Personally I’m enjoying using the MAF...
I agree with the DFCO being off causing the rich observations you are seeing, I?ve noticed it too. So what I?ve also found is that if I disable Closed Throttle downshift torque management on my 6L90...
Definitely true. I am thinking I will cut a little fuel first in the decel areas to see how the truck responds instead of enabling the DFCO again. I hope I can find a happy medium, thanks for the...
So I?ve definitely noticed a better fuel economy with DFCO disabled. My thought is that with DFCO on I move my foot off the accelerator and let it hover over the brake but don?t use the brakes many...
No worries there. You just set as you like it, make sure you have the right amount of fuel under load if you want to experience the possible power you can achieve. Use fueling to compensate the...
Thanks, but I’m just tuning for desire. I love to look at charts and graphs sometimes but the thing that really makes me happy is the feeling of a strong motor that can roast some tires if I want to....
Look at the fuel PE section. The settings for the delay to ramp in and the rpm staring value as well as the amount of pedal required will all play a big factor there. All engine torque management can...
