Added CPP to LS1b, what tables are affected?

[Jetmech442]

2005 LS1b, LQ9, 228R cam, headers. M6 trans.

I started with a mail order tune which got me running(good not great). The tune was setup to run without a CPP. I want to make sure I update all the correct tables now to reap the benifits. If you guys know of anything else I should be concentrating on, I'm all ears(and eyes, well, mostly just eyes).

I'm aware of TC and TF in Gear and P/N.
Rolling Idle is currently zero'd out...will this ask for "zero" rpm if I depress clutch and TC is active? Maybe just enter 800rpm across the board?

Base Spark in Gear{B5932}
Base Spark P/N{B5933} these are the same...should I change them?


Lastly, and keep in mind I'm new, after I complete RAFPN, do I need to redo now for RAFIG?


Thanks for any responses guys.

CPP?

Sorry, What I mean to say is that I added the Clutch Pedal Position sensor to the ECM(Blue connector, pin 35), hoping to get some better drivability by letting the ecm know that I've clutched in/out.

[Jetmech442]

any other experiences or advice from those who have added a CPP signal to an LS1b..or any ecm?

hello Jetmech442, im debating on doing the same thing to mine. did it help? what issues did you have to work out?

Made a world of difference. For my setup, LQ9, 228R cam, Lt headers, LS6 intake, T56 trans....I changed the following table:
B4310-Throttle Cracker P/N: added .50 lbs/min for 2-6 mph.

Wiring in the switch and changing the table eliminated the erratic behavior when I would try to roll to a stop with clutch depressed.

Theres a pic of the wiring in my build thread over on LS1tech...

thanks again. I'm running almost the same configuration except I still got the vortec intake. I'm gonna install the switch and wire for the cpp this weekend. is there any way you can send me your tune so that I may compare it with mine? I'm pulling my hair out. lol

thank you so much. that explains what I'm getting.

thread hijack- maybe I need a CPP?


I don't have surging- but at the beginning of some of the drives my truck will die when I push the clutch in and throw it in neutral while getting on the brakes(power) all at one time. Seems like this 'shocks' the system and it'll die. I do not have a CPP- I do have the brake system hooked up so my cruise works.

I'm basically wondering, is my problem no CPP, TC or TF?

I have rolling idle set to hang up over 1k. and basically as soon as I drop below my specified mph and the rolling idle decays the truck dies- like it literally has no airflow. MAP slowly and steady rises to ambient. Sometimes if I'm just moving the truck around back and forth it will die when I clutch in and brake at the same time. I'm nearly at a loss. Anyone have ideas?

When I first started tuning my converted car I was using the common 12212156 OS from a US based vehicle. My wiring loom was from a Monaro and didn't have a CPP provision. When I logged the TF/TC PIDs I quickly realised they weren't doing anything and I had some surge/stumbling issues after fitting a cam.

Rather than wire in a CPP I switched back to an Aus based OS 12225074 which cured my issues and the TC/TF tables started to work.

So I'd advise logging your TF/TC tables to if the values are actually working. If the values don't change then you may have to either wire in a CPP or try the 12225074 OS. If the values are changing then they probably just need some tuning to help.
