HELP! Supercharger ???'s

[CONRAD II]

Ok, I got my magnuson supercharger installed last week and picked it up yesterday. Tonight on the way back from dinner I noticed that my air/fuel gauge started blinking and was maxed out into the red zone on the right hand side. When I sped up it stopped blinking but when I let off the gas it started again. Next thing I know I look at my dash and my check engine light comes on.Am I running to lean or too rich? Can I still drive my rig untill Monday when I can have it looked at by the installers. Ahhhh! This sucks, I want to play with my new toy but I DONT want to grenade the engine!

If you have to ask these questions, then park the damned thing and wait for someone without their head in their ass to look at it. I bet if you did the work yourself you would know what to do.

Thanks for your help As@h*le! Go back to being GAY BOB. Any real help would be very appreciated! I don't want to take any unnecessary chances!

By the way if you want to be completely discusted click on GAYBOBS profile and look at his previous posts. FREAK. I think what he meant to say is he wants a head up his own ass. A gay hummer troll, thats a first for me.

It is possible that You have a problem with air/fuel on one side for many reasons. I would park it and if Your programmer will read the codes do so and clear it. Then see if it comes back on when You drive it slowly or normally to the shop. Do not go hard do not for a even a second to test and see if it will happen again. Go to the shop slowly or I should under no boost. If shop is far and You get any kind of lights have it towed the rest of the way. I'm sorry to be an alarmist but, a tow bill is a lot cheaper than toasting an engine.

Taz, thanks for the reply. I think if I just push the onstar button they should be able to tell me why the check engine light came on in the first place. I'm assuming its and air/fuel ratio problem but there's no way for me to tell for sure. When the gauge did go off into the red zone and started blinking it was under little or no boost and I was off the gas. The air/fuel gauge read normal once I gave it a little throttle. Don't know if that helps diagnose anything? What are some possible problems that would lead to this? Have you had any issues with your charger? Again, thanks for your help.

I agree. I think that the ECM will compensate a certain amount to get it to the shop. Under NO circumstances would I be allowing the supercharger go into boost.

Just out of curiousity, what programming are you using?

I (and my tech friend) installed my Maggie this weekend and used Nelson's programming. Unfortunately since I need a few brackets and stuff, I didn't get to drive my beast home but the only code that showed was a throttle position sensor needed to be reprogrammed.

Good luck, keep us informed.

I see your head is still in your ass. Sorry to hear that.

obz at WOT at 10lbs. I read rich. I did not have laptop so i could not get the wideband numbers. I use a nice set of lights one for each bank of engine. They have a nice safety margin in them as they read the color in general ahead of the actual AF condition so that if it is getting to lean You can at a glance under WOT see it like You would be glancing at any guage. They are run off factory AF sensor. I will be using the wideband for serious tuning shortly. I can with on board computer put the actual wideband numbers up on the dash screen with HPTUNERS software but, i have to look down (bad) and to the right (bad) to much so thus the 4 light system one set for each bank let's me see looking straight ahead.

I'm running the stock TB at this time. Not sure where i will go with that yet.

The tune was actual the kit tune which strangely the computer was able to get a good enough reading off the MAF and mix enough fuel for the first tune and launch in an awesome run. Then it did not actually act like it went to limp mode because it would still run real good and all gauges looked Ok as far as safe and not hurting anything. It was just wierd as I could pull the tune and put it back in and then another great launch.

We have put the kit pulley back on it for a good while and with headers all the add ons it runs good enough if i just were not into making it go and continue pushing it the mall queen runs really good with kit tune etc. at 6lbs. of boost that with an HPTUNERS tune at 6lbs. it would be a monster. I like to see what kind of beast i can let loose out of "The Beastly Beauty"

Hey Gay bob stop reading my post your arse. If you were not such a prick you would have something better to do. Go sit on something with AIDS and spin!

Taz and Obz thanks for all your help. I got my truck back and the shop said that the oxygen sensor had come loose, causing the check engine light to come on. Also, they had to change some programming in order for the volant maf to work proper. I drove it about an hour today to the country and it never varied much below or over 14.5 on the af gauge. I know that my gauge reads lean to the right rich to the left. My tuner told me that variance is normal though. On the way back tonight I averaged 14.5 but under throttle the number usually dipped some and sometimes when I backed off the gauge would read up to 16 but never stayed for more than 3 secs and dipped instantly when I gave the engine some throttle. The truck ran great the entire time and my check engine light did not come back on. Am I still in dangerous territory? Am I being paranoid? Dose the problem sound solved?
