I got my innovate mtx-l wideband installed. Worked on it all day to get looking good. I eliminated the aggravating ashtray and did a custom mount there. Removed the outer part of ashtray, cut gauge hole, ground clearance around everything to make it fit. Blends in nice. Looks really good and the silver bezels that came with the gauge match great. I'll take some pictures tomorrow.

Went out to make a few runs. Couldn't datalog due to not having a serial to usb adapter yet. Just visually running down the road 14.7-14.9. First hard run, car was hitting 9's before cutting out at 5k. Apparently running lean is not my problem. Made several other runs, all hitting in the 10's and 9's at top before shutting down. I'm going to do a the diy belt wrap tomorrow just to isolate something else. The dang car just seem to be electronically shutting down and disengaging the supercharger pulley or killing the timing. I'm about to stick the original pulley back on just to see what happens. Did not have a problem until it was installed? This one has me stumped.

do these cars have some timing cut when it goes uber-rich like that? just a thought


edit: do you need/have to calibrate the O2 for you wide band......like a free-air cal before installation?

 

as he said... 9's - 10's AFR is PIG rich...... no calibration on the sensor... plug and play...

rtmopar, glad you got the gauge in and verified your AFR's.... have you ruled out torque limiter???

 

LOL....thats what I meant, its late and im at work. sorry about that

 

By the way, the MTX-L does require a free air calibration. I own one and calibrated mine this week.

 

ooops! Sorry.... my zietronix was plug and play...

 

Calibrated the gauge in open air per instructions.

Jerry said the torque limiter is turned off in the tune.

 

Forgot to mention, I had the resonator remove when I had the o2 bung installed. I don't like it. Its not that is that loud, just the wrong kind of noise. Bad noise right at 70mph. Quiet on the idle and at cruise at at other speed. Acceleration sound more aggressive but its just not my kind of exhaust note. This is coming from having two vettes with no mufflers at all. They sounded much louder but better that this. Might call the muffler shop to make sure they don't chunk the resonator.

 

How much boost are you seeing when the power drop occurs?

 

It's hard to tell as the gauge is hard to read when the car is pulling like a train. Had a friend in the car watch the ultragauge. It showed 18.5 at 5k before the car cut off. Before the gauge, I measured the supercharger pulley just to make sure I wasn't accidently running stacked from the prior owner. I would think belt slip would be gradual rather that the car losing everything. I wonder if the supercharger clutch is letting go. I guess I could check clearances and then maybe straight wire power to it.

 

Its easy to adjust the overall F/A mixture by controlling the Fuel rail pressure. Seems that you should adjust the pressure lower, say start at 60 psig. Rob has adjustable fuel regulator set ups, just ask him and tell him that I suggested the external regulator option. I was at 9++ once, when I was doing pulley testing, trying to get rid of lean - - went overboard, fixed now. Enjoy OBTW Pig rich was my term back then.....Woody

 

NOTE: If I recall correctly our cars don't like it when you do that.

 

Thanks for the tip, no straight wiring. I will however try your belt wrap trick today if I can find a pulley at autozone.
