I had an issue with my ecu not coming up ready so i wanted to try a stock file in the car and see if it will scan properly.

I checked the hptuners site but i wasnt sure if those were actually stock, aside form just saying there were stock.

serik21

Are you talking not ready for state ob2 test cuz if so I seem to have same issue

liqidvenom

yep, do you have the stock tune in your car?

serik21

no i dont have stock tune but my tune was made with maf turned off and im always getting a po103 maf to high, but no check engine light and 02s are not ready so far put 187 miles on the car, trying to see what might be causing this, how about you how much miles have you put on are you having any other issues?

well i put about 10000 miles since i got the tune. and i have no codes. im wondering if my playing with hptuners while waiting in line to be inspected was the cause of me to fail.

serik21

Probably. U can go to autozone and check with the scanner to see if it's ready but you will need atleast 200 miles cuz last time I checked mine was not ready at 195.

You went with a speed density tune then, you shouldnt be getting a code for the maf in that case.

serik21

itsslow thats what i thought to but car runs fine check engine light isnt on, just trying to figure out whats the issue, any ideas? tried a buddies ls2 maf still same code

Speed density tunes can still utilize the maf, have you tried cleaning it? Have you recently re-oiled a k&n filter or anything?

Nope, that code HAS to be set or the pcm will not fall into speed density. Usually you just tell the computer not to show the check engine light. It sets that code because you (or your tuner) set the maf fail to 0hz and since the maf is still hooked up anything over 0hz sets the code. I've been running open loop SD for several thousand miles now and my O2s are never ready as well since I'm not using them.

Speed density tunes to not use the maf at all. GM uses a mixture of speed density and maf stock, but to run speed density you are telling the computer to ignore the maf.

It sounds to me like your car is performing exactly like an SD tune should. There is probably another reason for the ecu not ready. You sure you have the car in the on position when trying to hook up HP Tuners? Who tuned the car and with what software?

serik21

How would I go about to get the ecu in the ready mode?

Are yall having issues hooking up the hp tuners scanner? or are you trying to get your car inspected?

mine was getting my car inspected, but i think i did something while waiting inline using hptuners. i went back today and my car passed.

But i still want to get my hands on a completely stock ls6 file if possible.

Inspection stations arent allowed to pass a car until the ecu has completed all of its tests after clearing a code or flashing up a new tune. That can take several days and several heat cycles. That is probably the reason for the "not ready" issue.

I wish I could help you on the completely stock file. When I hooked up my HP Tuners for the first time, I found out mine was not only far from stock but fubar as well so HP Tuners couldnt do anything with it. I started with a buddy's "stock" file that already had some adjustments in it.

serik21

I'm just trying to get it inspected have 3 days of driving and 180 miles total mostly city driving. Still not ready

Sell you a stock tune

serik21

I don't think it's in the tune. Same tuner tuned my buddies car and his obd2 is fine. DONT know how many miles he put on before system was ready

I have a stock tune at home on my netbook. Won't be available until after 18:00 CST though. Glad to help out if you need it. It's from my '05.

serik21

any body figured out a solution for this yet?

Here are 2 you can look through and compare. They both are supposed to be stock but didn't come from my V so no guarantees.
