Puzzled by SM numbers

[87-WE2]

Scanmaster installed. Drove the car around a little bit and am puzzled by the readings I got.

BLM's are 128 at idle, but when driving are no higher than about 110 (this indicates a rich condition, right?)

O2 readings are all over the place during normal driving, but when I get in it, they go sky high to about 850 (this indicates a lean condition, right?)

These two conditions have me baffled as BLM's indicate rich, but O2 indicates lean. I can only get about 9# of boost without KR. If I put my foot in it, I can get KR above 5 (easy).

Please note I have GREEN STRIPE injectors, contrary to stock as my sig would indicate. I also have an old ATR Pitbull chip with WAY too much timing.

I do have a new TurboTweak set up for 60# injectors, but I haven't put the 60# injectors in yet. Once they go in, the new chip goes in.

Should I just ignore this & not drive the car until I get the new chip & injectors in?

The car surprisingly enough runs coolant temp of 175-ish when cruising, up to about 190-is in stop & go. I thought I was running hotter than that and was thinking about an ALRADCO. In light of the lower than expected coolant temps, I'll probably hold off on the radiator till later on.

When is teh last time you replaced the o2? How is the cross counts on it?

850 is RICH low numbers are lean, high numbers are rich.

I would not pound on it or try and get too deep in diag until you get your TT/modern chip in.

I think the sensor is OK - CC's go up about 10 or 11 per frame. Largest jump I saw was 12.

I guess I just had the numbers for the o2 wrong. I was thinking high 02's were lean.

Since high o2's are rich, that confirms the low BLM's. I'm running rich as hell and that could explain a stumble that I have at 1100 - 1500 rpm.

I'll drive as little as possible till I get the new inj's and chip installed.

Thanks for your help turbonasty!!!

So Close yet just a little more money...

When you have TT Chip & Injectors. what type of spark plugs are u using and their gap... Two things stand out that I had problems, my spark plugs and gaps and MAF/Translator then u can add lil here or there with base setting rich or lean a little... I use NGK UR5 gapped tight at .030

A LOT of my problems are always related to poor fuel quality...
