The haltech doesnt have the change the profile correct? Only if you adjust the cam phasing will it throw the codes?

It looks like the quick and easy answer is Osiris. I was going to test to 1000 miles before posting success or failure... (keep your fingers crossed). I accumulated a list of CEL codes running the Haltech over a 2 month period. I went through the FSM and added on all related codes. I sent that list to UpRev, 1 reflash later and voila!
Once I'm done with this 1000 mile test, I'm going to remove the MAF (I had them remove those CEL codes also) and see what happens (I use a Haltech ATS wired into the MAF wiring so the stock ECU still reads that).

I've thought about just eliminating the codes using Osiris. I'd rather find out why they are triggering and see if they can't be resolved without physically eliminating them.
Additionally, there might be other consequences for removing these codes in states that use them to determine emissions tampering.

Regarding P0011 and 0021, they are both related to modified intake cam timing. These are caused by cam timing being tuned outside of the factory range. To avoid these immediately you have a couple options:
1. Keep improved cam timing and use reflash to erase the code
2. Adjust cam timing back to factory range or splice wires to bypass Haltech Cam Timing control

Or, do you happen to have a map that has the stock factory cam timing, since I no longer have it anywhere?

I do use stock widebands for closed loop feedback so it would be nice if the Haltech could detect and indicate stock wideband failure or trigger a failsafe of some sort (now that the stock ECU must remain silent on the subject
![Smilie](https://my350z.com/forum/images/smilies/smile.gif)
That makes sense that removing the Haltech fixes the CELs since the closed loop feedback is going to look broken from the stock ECU's perspective while the Haltech is controlling it. I even tried to change the AFR targets using Osiris before resorting to code elimination and that didn't work either.
I don't think this code elimination would be detectable by the emission testing computer, but I could go test it out... (I have this friend who has a friend

Dave90TT, I cannot think of anyway Haltech can modify cam timing and not get the stock ECU to throw codes. If you bypass the Haltech cam controller as Hal suggests, you should be golden, but of course you don't get to control cam timing. I wonder if I can read stock cam phasing with Cipher - Hal do you know? Setting up a default map that matches stock might be valuable for customers that don't want to mess with rewiring.

That would be really sweet Hal. Your 32 in/out module could be used to trigger warning LEDs/alarms so I'm not so concerned with this feature anymore. Intercepting CELs codes on the CAN bus sounds complicated, but I wouldn't put anything past the abilities of Haltech's engineering team, especially with you helping them out. ![Smilie](https://my350z.com/forum/images/smilies/smile.gif)
Over 900 miles so far, no CELs. Plenty of 14 psi runs.
My EPA sticker expires in Oct, but I'm going in early for inspection to a mod friendly dealer to see if they are happy passing it as is.

It's not fuel cut. It's just that cell in the fuel map is off. Closed loop correction using the stock widebands is slow and quick blips in the throttle will go uncorrected. To fix it, you really need to fix the cell that is out of whack in the base fuel table. Turn on trace (hit T on the keyboard) and blip the throttle. You get a trace of which cells the EMS used during the "blip". Increase fuel for those until the hesitation goes away.
The other piece that may be off is the enrichment sensitivity. This is a quick burst of fuel when you tap the throttle. It happens too quickly to register much on even an aftermarket wideband so you really have to tune this table by feel. The key points are that small changes in throttle require larger % changes in fuel and this compensation is needed more at lower rpms (by 4k rpms it should read 0).
When you do get tuned, ask to go out on the road (you drive) with your tuner tweaking in the passenger seat and try to get it to hesitate with multiple throttle blips. Have him dial out the problem spots (having a wideband in the car is a necessity for him to do his job properly - and the stock widebands work well only from about 13-15 AFR).

The Haltech makes it too easy to get a "perfect" tune with large corrections from closed feedback. In the main setup menu, you can specify how much correction the closed loop system is allowed to impact the base fuel table. Mine started out at +/- 20%. And although the numbers look great, transient throttle driveability definitely suffers if using the slow, stock widebands. If you've got aftermarket widebands, maybe that'll work. I personally feel the best solution is to dial in the base fuel table under vacuum using no more than plus or minus 10% closed throttle correction. The car drives like a dream if you can dial it in to that level (I'm re-tweaking to get it to +/- 5% only). Not to mention improvement in fuel economy...
