Do you have a K&N oil filter? Spray the MAF down with the proper cleaner and then try to see if it detonation.. To much oil will cause false readings of air flow. Im having a problem with that in my 03 sierra. False readings from the MAF not being right, so the computer never compensates the fuel for the airflow.
beside very slight pinging,in the rpm range of 3000-4300, the car runs great now, as for the permanent fix, i''m waiting to hear from hahn, i think i have to send the ecm back for a reflash,for the slight pinging........ as for the turbo???????????????
The best and safest thing you can do for your engine is to run the water/meth injection. It will eliminate your ping. I was king of the ping at one time. That completely cured it. Same thing with JT72, tons of ping cured with the water/meth injection.
Take the car for a drive, and in third gear hit the throttle all the way down. Post your boost and air/fuel readings at peak. I am wondering if you are getting some boost creep
there. As Clear said, you should not be boosting more then 8 psi.

While this can be an interesting and effective approach for some at higher power, it's definitely not neccesary at this boost level. We'll fix him up, guys. It's what we do best!

NOT WAITING ANY MORE!
Meth is not the answer on this one. Meth should be used to lower charge temps. I would never sugest
meth for fueling, that's a dangerous way to go. I wonder if the pinging that you have in that rpm band that you listed is due to the piston slap table that is in the ECM. Once that's "taken out" our cars will run lean in this rpm until fuel is added back in. If left in the car runs really rich there and causes that dip that a lot of us see on the dyno.
haven't heard from hahn yet, what to do about the oil problem, they where to get back to me but have'nt heard anything yet (i think aaron & bill are talking about it)
my son & myself are taking an autoxing program may 4th, so i'm hopping to have this fixed by then, before the autox season starts. i have to ship this back from canada, which takes time. & how much time, will they need?????????

Hi Doug! We've been in touch with your installer, and will be calling you this afternoon. Thanks!

hey bill, i talked to aaron & he wants me to send the turbo back to you, no problem there, but what i'm trying to find out is what to do about the pinging, from 3,000-4300 rpm,
step on the gas entering the freeway, & ping, ping, ping....not sure if i should drive it like this or not? aaron was to get back to me about this on monday & haven't heard anything yet, he was going to talk to you about it, because he seemed worried that it wasn't a common problem in the reflash, he was thinking that maybe it wasn't done.
i would like to send both back at the same time, since i'm in canada.
iv'e tried to call a few times, but can't get through.

Got it, Doug. The phones are rockin', spring has sprung, and EVERYONE wants what we got!

finally, 2 months later after i first opened this thread, i got my answer from hahn,(with car sitting at turbo installers shop wating for their 1 week turn around) hahn told me my turbo over heated, & got toasted, aaron says the cause he feels was that the turbo never got sent back for the reflash to 91 octane gas(from 93 octane), & because of this it over heated.(i'm absolutely pissed) if you look at one of my previous posts april 20/07 post #4, it clearly states that it went back for reflash, but hahn wants a postal receipt to prove it. now just where did i put that? in a another post in october, i talk about the turbo having blow-by, hahn answer to that was if it's not blowing the blues, don't worry about it.(within warranty period,but now it's not) well i guess it's time to worry. they tell me they have no record of a reflash, & they keep mentioning something about an ecu upgrade that was done. i don't know anything about this, so my guess is that they did this upgrade, & did not do the reflash to 91 octane gas. so they say it's my fault.
to try to get rid of the pinging through out this ordeal, weve tried high octane gas, twice,(which worked) changed plugs, (which the dealer was not happy doing, because the plugs are longer, the cover does not fit properly & they say moister will get in there) & refashed
iv'e tried to get a hold of bill himself to no availe, iv'e faxed him, told aaron@hahn i want to speak to him, & e-mailed him(but might have e-mail wrong place)
the cost to me to have this turbo kit, totals to $9813.62, & the turbo is no good, so i need another one of those too, i will be posting the break down, & invoices to back this up, but i don't know how to do it, so i will get my son to post it for me(comming soon,new thread)
just to let people know (especially kids) to the true costs of having a kit. iv'e faxed this list to hahn expecting a phone call from bill, but no.
this car i have is off the road, as much as on the road, do to this kit, it might be a good system if you were a mechanic, which i am not, i have to rely on the professionals for this.
so all of this & a locked ecu to boot!
doug:
The Mitsu 16g is a fairly cheap turbo. Seems like the least painful fix would be to send your ECM back to Hahn (Vector) for a re-flash and set to 91 octane (if that's the best gas you have). If you have 93 available - use it. Find a 16g on E-Bay and have your installer use your compressor side case on the new turbo (for air out size & position). Set the wastegate actuator rod (shorten) to produce 6.5 lbs boost to begin with and put the car on a dyno so you can adjust the boost while monitoring the afr.
Otherwise, for the greatest adjustability and safety you may want to check into getting a Greddy boost controller and an afr gage - look at the PLX DM-5 AFR wideband.
Good luck!

Listen, I am very sorry that you are having such a bad experience with your car. Please don't take this post personally, but there are a lot of things that you are saying in your posts from the beginning that don't make sense. I have highlighted those items in this post.
You talk about the re-flash of the turbo, to 91. What about the installer? What was said in those conversations with Hahn about it? It doesn't sound like the installer was the right person for the job. A good installer that has done these types of setups, (and I don't just mean on our cars) should have been able to quickly diagnose the issue before it became a problem. Sounds like all the troubleshooting resulted in things getting broke, instead if he was better experienced situations could have been avoided. Did you have a boost gauge? How about an AFR gauge to monitor A/F ratio?
Enough research and exploration wasn't done before all this was put together. Pinging issues can be easily solved or taken away safely (turning down the boost) before problems like this arise, until the situation has a fix. It doesn't sound like the installer took those steps. MOST KITS ARE NEVER A BOLT AND DRIVE. Some get lucky most don't, and the person buying the kit as well as the installer have to be ready to tackle these situations with KNOWLEDGE and RESEARCH before hand.
It takes failure to learn sometimes and this is one of those situations. A lot of people that do these things to their vehicles learn the hard way, hell I know I've had my share, but along the way, I put things into perspective when doing it again, and researched all the parameters of what could go wrong first, and what the best fixes are. Personally I don't think I would go to an installer that didn't have tuning abilities, or at least have a tuner nearby that could hook up and monitor and change what needs to be changed to make a safe running vehicle. Again please don't take this post personal. Hopefully if there is a next time you will be more prepared.
My Tech Support people brought this particular case to my attention on Thursday of this past week, asking for my assistance. I asked that they bring me all the involved data and let the customer know I'd be reviewing it first, then replying.
On Friday, I sent en email to Doug after reviewing this information, apologizing for the delays and offering to assist him. I'm confident that we can reach an agreeable negotiation.
