Came here looking for some advice and to make sure my tune isn't going to blow up the car. Recently swapped an LS1 (LM7) into an RX8 and I'm going through the rigors of tuning.
I've scoured the forms did things like Russk's idle config to make sure everything is good for Idle, also went into the repo and pulled a few similar vehicles to grab bits out of that make sense and finally I've watched LowbuckLS and High Performance Academy's videos but I didn't want to overwrite the base config with a bunch of cobbled together junk.
I have my initial stating point, but here is what is in this thing.
2000 Chevy Silverado, LM7 5.3 v8
- Jegs, 228/230 112 (.585 / .585)
- 862 Heads, LS6 'Blue' Springs, Trunnion Upgrade
- 92mm DBC Throttle Body, no holes.
- LS6 Intake
- EV6 30lb
- LS3 Camaro Shorty Headers
- Full dual 3" Exhaust, no Cats
- Full Fbody Camaro Accessory drive
- 4L60E with the Corvette Servo swap
- Yank 3600 Stall
Now to put it nicely, this is my first time working with an engine with a Cam so I'm a little new in that aspect, as well as Auto transmissions in general, I've always driven manuals. Anyways, the tune I have in it seems to drive quite well, but it's very rich at idle just by smell. One thing I do not have is a Wideband, I'm working on getting one shipped now (If anyone knows a good place to get the Wideband bung welded up in houston hit me up!)
Some things I'm noticing:
- Smells rich at idle
- Slight 'Cam surging' at low rpm
- Shift points seem to be ok, but it kicks going from 1 -> 2 /// 2 -> 3 & 3 -> 4 is almost not noticeable.
Here is the tune file and a log file. Just want to make sure I'm on the right track or if someone sees something glaring I'd appreciate a heads up! Not sure if I'm missing anything, but I'll get it to you if you need something extra.
