I'm slightly confused regarding which codes are 'real' and which are a result of the Haltech/Osirus. I recently replaced my spark plugs and an 02 sensor which was throwing a 1288 code. The light stayed off for a bit but it seems it's back. No big deal, previous tuner turned off the O2 sensor readiness via Osrius, so I'll do that again.

While pulling the codes, I got P011 and P022. The car runs fine, no limp mode, runs strong, idles and starts as it always has. Should I replace parts associated with this or is it not a 'legit' code/problem and more of a result of the Haltech/osirus? The ECU was reflased with osirus again since I could not get my key from old tuner that is out of business, I'm not sure if P011 and P022 is a code I should ignore with my set-up.


Anyone have any suggestions?

 

What's your setup? I have the same Haltech/Uprev But my CEL's are different...

 

Powerlab single, Haltech, osirus. what codes do you pull

 

those are intake valve timing codes. to be expected with Haltech in control...

 

aahh thanks

Is that something Osiris can override to keep the light off? I never saw a code come up on the original tune and flash, so I think it might be a yes. 02 sensors were disabled, not sure if this was also disabled before.

 

Whats the main point of having the Haltech and Osiris? I ask b/c my car is going to be tuned using the Osiris for my Momentum kit. But I have a haltech Plat pro(bought for my TN kit never installed). No built engine just Kit on Vq. Thanks sorry for hijack

Haltech has FAR more features than osiris.

Things haltech destroys osiris in:

Does not need an upgraded maf
Internal boost controller that can be adjusted against any obd2 parameter (boost by speed, ect) with overboost protection and boost cutoff (for knock control)
full start up parameter adjustment (cranking enrichment, timing, post start enrichment, etc)
If you have dual wideband it is integrated and used to control the car and tune with. OEM widebands (if you have them) only read down to 11.25 and aren't as accurate.
Knock control
On the fly adjustments, no turning the car off to flash
Onboard logging with adjustable recording trigger (choose what you want to trigger the logging)

Just to name a few that stand out. I know people talk about the cost of osiris but to get end user tunable osiris (700$)(new maf needed: 260$) with widebands (300$) and electronic boost controller (300-400) you are already in the range of a nice used haltech and not too far off buying brand new.

If you just want 1 person to flash it and not do anything else then the 300$ flash plus tuning fee is the way to go though. I would just make sure the tuner uses the dyno wideband and not the crappy OEM wideband (for 04.5 and newer) cars. When I tested an 05 against the calibrated dyno wideband it was off by quite a bit. No big deal on an NA car but catastrophic on a boosted vehicle.

 

With Osiris, you can disable the irrelevant DTC codes. These are the codes I disable for my 2004.5 G35 coupe (because they are either irrelevant or helpful in other ways ):

P0011 intake cam timing
P0021
P0171 system too lean bank 1
P0172 system too rich bank 1
P0174 2 lean b2
P0175 2 rich b2
P0441 evap ctrl sys incorrect purge flow
P0442 evap ctrl sys small leak detected
P0456 eval small leak detected
P1148 closed loop b1
P1168 closed loop b2
P1276 af sensor high voltage b1s1
P1278 af sensor slow response b1s1
P1279
P1286 af sensor b2s1
P1288
P1289

 

wow, I guess i'm a lucky person. I haven't had a single code with my haltech. No codes disabled either.

 

0011 Intake cam timing
0021 Intake cam timing

These are soft codes that in most cases do not trip the CEL, but are stored in your vehicle if you check with a scan tool. They do not mean there is a problem if you have a Haltech Pro Harness system. You do not need to take any action.

The stock computer just noticed that it's commanded intake cam timing does not agree with the actual cam timing. Reason for this - Haltech is controlling cam timing.

 

Thank you Guys! I already own the Haltech plat pro. I will prob just keep it and get it installed. I bought b/c of the overboost protection among other things.

Now why pair the both together?

Chris
the reason I bought the haltech was for the price. (Osiris & HKS boost controller = the same for my haltech)

 

Can uprev disable a po420 cat code?

 

you can turn it off with Uprev, but you cant change the SRT readiness of it.

 

Ok so for emissions it will show its working then

 

thank you, that is exactly what I needed.

 

also thank you, great info.

I guess you have to feel a problem after all of these codes no longer mean anything and trip for 'normal' situations

 

some cars require the rev limiter to be raised from osiris before haltech can raise it. Mine didn't oddly enough. Same with top speed limiter.

Also, you can remove those codes if you want.

For me the only reason I have a flash is to keep my idle at 1050. Cipher only raised it to 900 for me and that just wasn't enough to keep it idling smooth with my heads and cams.

 

Haltech/Osiris is worth it. I had a UTEC and the car drove like a beat-up POS. Surging with no power (not sure what waseven happening), hot start problems, jerking all over the place and in and out of boost. Absolute waste of metal, plastic, and time.

Osiris is great for the code control, I actually got through emissions with the reflash that is popping my O2 sensor codes after driving for a while...not sure how it happened, but I got a NJ state sticker.

 

Thanks Guys! Ill keep the Haltech. Hope you get everything figured out UMW.

Chris

 

There's only a few codes you need for Emmissions, When you disable them It just puts the disabled code in a state "Not Supported".
