Thanks Mark, yes Eric got back to me and said it should work, just a bit lower on boost. Getting some pl issues sorted now and then will get knock issue sorted

Its all coming together, getting headliner delivered today and will have all interior restoration parts on hand to complete interior!!

Never thought of that, I can keep the sm hooked to orange wire so it will work also. 

I did figure out I do have 60 lb injectors so that theory is out

Doing some research, evidently there is some capisitor mod that needs to be done to an older logger ( can't find any solid direction on it) and then a reflash to get the SM G to work with it. I have a post in to Eric asking whats up.

Tried to hook up PL and when I turn they key to on but not start car the SM just jumps numbers all over with O2 and knock readings constantly changing...... .I think the pl is junk unless you need to do something special with these new round SMs

Had a little time today dug into cruise not working. Prior owner had a checkvalve in backwards to no vacume to it.....fixed that and cruise works great. Thought maybe I would get lucky and that check valve was causing my knock issue...nope. if I run her at a steady 7-8 lbs of boost I can watch the SM slowly lean down until knock starts. I checked fp rise before and it was good.. Its obviously sucking in un metered air from somewhere but I can't find it. I have covered this motor in carb cleaner to the point of being seriously concerned about it starting on fire and no rise in rpm? I'm running out of things to check. I was told it had 60 lb injectors but maybe they are not? They are Moto....someth ing, I can't read the rest and the only common numbers on them are INJ- gas-006. Assuming if they are smaller injectors the ECM is thinking its sending the correct amount of fuel but its not enough so it leans out???

Thats an interesting video. Problem is now it makes me think I need a wideband!

Eric says chip should be fine on 91 octane at 15 lbs boost. Going to put everything back to defaults and start from scratch. Going to try to get powerlogger working, that would be a huge help also

Well, no suprise, this old girl is determined to be dificult. lowered timing in first/second to 17 and also in 3/4. added 10% WOT all gears fuel, turned up FP to 45 hose off for good measure. Still knocks, cant even get to WOT long enough to have SM retain info. SM knock got up to 4.6 when I lifted. I'm thinking I should just get a chip burned for this cars specific's? I tried to roll into boost in drive from about 40 mph also and cant even get to WOT before I need to lift because of knock.

another weird thing, after one pull, slowing down from 90 mph'ish, foot off gas, O2's read 0 for the longest time, then blipped the gas and they came back???

I was thinking also,
car has a TA 49 turbo and a 3 in DP. Im guessing the chip was for a stock set up so I probably have to add alot of fuel also?

Fuel pressure is rising

Chip says 20 degrees - 18 degrees

Also 16-18 lbs boost, seem like alot of boost for pump gas??

I can hear it as well so pretty sure its real, should I set 1/2 gear as well? I punched it from a stand still and instant knock.

Also not sure on the timing marked on the chip, will pull it and check first.......th anks!!
