Halltech Stinger and codes
Is it normal for a Z06 to have the "check engine" light pop on after a Halltech Stinger install?
Does this eventually stop or is this something a tune would take care of?
What's the cause of the code?
I've had my Stinger intake for a few weeks now. Light came on, I checked the DIC for the codes and erased them. Light came back on about 2 weeks later.
Thanks,
Mike G.

I had the same issue when i put on my Stinger. What code are you pulling, a Lean Code? That's what i pulled, and it would come on & off about every few weeks. Check to make sure there's no leaks. Leaks will cause that. And if there's no leaks, then you'll need to do what i did. Which was the Cold Air Mod. After that, no more codes. And having the car Dyno Tuned helped out big time. Good luck!!!

The only performance mods i've got is the Stinger w/ cold air mod, X Pipe, & Corsa Cat Back Exhaust. My car dyno'd at 387hp/378tq to the wheels.

Sounds like this one is handled . . . I only had my stinger for a few days before I did the headers/tune, so I haven't seen any codes.

Just my .02, buying a tuner package and learning how to use it is mod money well spent!

The Cold Air Mod helped cause it gave the air a more straight shot to the filter, so less turbulant air kept the code from popping up again. After fixing the leak, and several pulls on the dynopack got me the horses i lost and then some! So make sure all your fittings are tight!

I can buy in on the loose connections creating the lean code and that's what I would be looking for if I had that problem. Any un-metered air on the intake side will create a true lean condition. Exhaust side air leaks may cause the O2s to think the car is lean when it's really not so that's always worth checking too if you've done any exhaust work.
Still can't sign up on the cold air mod though but that's just my opinion and we all know what those are worth

I do disagree on the airflow though. At idle there's little to no difference. Anywhere from about 1500 rpm on up you should see improved airflow (more grams per second) with a high flow filter and better air bridge. I'm basing this on scans I've run on both an fbody and the Z06. I don't think the "cold air mod" adds anything to that but I haven't actually tried it or seen anyone else that's got scan data on it.
I would really like to know what normal IAT temps are for anyone running one of the CAI's that require cutting the shroud. Do you really get any cooler air? Seems like the Z should have enough airflow that this wouldn't help much.

An occasional CEL/lean code seems quite common with many brands of aftermarket air intakes.
I ran a CAI for most of five years on two C5Z06s.
CEL would appear very occasionally under light load conditions, never under WOT. I'd check codes and find it with an H (history) NOT C (current). So for me, the provoking condition was transitory.
I alway ensured the clamps were tight, and they were. Almost always, the CEL would clear itself on th next restart. But the lean code, of course, was stored until cleared.
If you follow that pattern and feel no stumble or misses at WOT, then you should be like most of us running aftermarket intakes.

I have not seen a code related to my Stinger install after 1000 miles or so. I used one of those fat shortie screwdrivers to get the clamps tight as nothing else seemed to want to get the job done right. Didn't use a procedure, just switched it out with stock and let her warm up on idle before I took off. The car shook quite a bit while the computer adjusted but smoothed out before I took and did a half hour cruise. It's still working fine but I plan to get a tune before long just the same. Don't think she's ever had one.

My IATs drop quicker with a Vararam than they did with a filter (OEM or aftermarket) behind the should. Both setups will eventually get to the same IAT, the VR just gets there quicker.

Well on the way home from A&A yesterday, the check engine light lit up again. I have to admit, I didn't check and see if everything was clamped down tight. I'll pull the codes and see what they are.
Quick question, last time I checked and all the codes had an "H". If the light just came on, would it have an "H"?
On another note, yesterday I dynoed 357.85rwhp and 342.33rwtq with just the Halltech Stinger. Do these numbers sound right?

Alright, here are the codes:
P1626 PCM Theft Deterrent System Fuel Enable Circuit
P0174 PCM Fuel Trim System Lean Bank 2
P0171 PCM Fuel Trim System Lean Bank 1
C1222 TCS RF Wheel Speed Sensor Input Signal is 0
C1221 TCS LF Wheel Speed Sensor Input Signal is 0
C1248 TCS ???
U1000 SDM Loss of Communication Undetermined
U1040 SDM & IPC Loss of Communications with TCS
U1160 HVAC & IPC Loss of Communications with LDCM
U1064 SDM, IPC, RADIO, HVAC, LDCM, RDCM Loss of Communications with BCM

U1016 TCS, BCM, SDM, IPC, RADIO, LDCM, RDCM, SCM Loss of Communication with PCM
U1255 BCM, HVAC, LDCM, RDCM, SCM, RFA Serial Data Line Malfunction
Any reason as to why I'm getting these codes? Nothing popped up before I installed the intake. The check engine light had popped up one time a couple days after the install and I cleared the codes. These are all new.

Were it mine, I'd clear the codes and go for a test drive; do some WOT; then stop and check the codes. This time noting the C and H.

Do the P0171 & P0174 codes eventually stop popping up?
