I have similar issues too. I have changed out the cable to the scanner and the one to the computer with no luck. Randomly it drops connection; full throttle, driving around town, idling in the...
I'm obviously confused... Is this because of the SD tune?
So, IAC Step vs Effective area is left stock, Scalar changed to 90mm TB, log new base airflow and add to tune (initially add some air to...
I have been fighting idle issues ever since I installed a LS2 TB. When I originally got the car back after an engine build, the ETC Scalar was set at .0330. That is incorrect for a 90mm TB so I...
Any update on this, I have the current Beta and it doesn't save. I'd like to use the outputs for lean AFR under boost.
I ended up replacing the LS3 with a LS2 TB, no more code.
I had my car on the dyno and it started throwing a P1516 Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance code with a 09+ LS3 TB installed at WOT (GM 12605109). This is...
I have a fully built 4l60/4l65 tranny in my vette which has about 900rwhp. I blew the last tranny at the drag strip (lasted several year) and upgraded to one with better internals. I'd like to give...
What do you think is a good starting point, lowering it 20%? I guess that is at least a starting point....
Since switching from my stock LS1 engine to a forged LS7 engine, I have not seen any knock retard. The conversion harness that I used placed the stock LS1 sensors (located under the intake) to each...
That make more sense, I'll work on that. Thanks.
I changed my IPW from 0, Injector Dynamics data, to 1.4msec and the car died as the after start enrichment went to 14.68. I tried .7, car ran but the AFR bounce around a lot and the idle wasn't very...
All the injector flow data is from Injector Dynamics who makes them. They sent me the table specifically for the car.....
I'll try adjusting them. Thanks :cheers:
Thanks guys, I've even tried disabled the DFCO on a previous tune hoping that would do something, no luck...
For some reason, each time I go off the throttle at speed and the car drops to about 50 kPa or lower my fuel ration goes to 11.7ish when 14.68 is commanded in both OL and CL. I’ve tried adjusted...
Thanks:cheers:
What should I use from the pull down menu for my new engine (LS7).
I have the cylinder vol set for the 7.0 L.
Bill,
Here is my old tune prior to the 2 bar and 3 bar OS. Anything you can do to help is appreciated.
Anyone?
I upgraded from a 2 Bar OS with RTT to a 3 Bar and there was no RTT option. Did I miss something or is it not available?
I am changing my external pump to a Aeromotive A1000 and 1000cc injectors. That should fix everything
Well my injectors are not holding up to my new engine. I am currently running RC SH-750s. At 6200 rpm the duty cycle was up to 112% with a 11.5 afr.....
My external fuel pump is set at...
Got the P0068 code fixed by lowering the VE and the injector flow 30%.
Thanks for the help :cheers:
Idle is steady +/- 50. No real variations greater than that. No idle surging, just some at low throttle positions while driving. I'm still working that.
Thanks,
I'll give it all a try tomorrow :cheers:
