can anybody see anything wrong with log?

[bpman1234]

went out and did acouple of blast about 3/4 throttle it has a dip right when i stomp on it like everything goes dead my 02 guage turns off no signal and also on the logger for a split second then everything works and the car drives any suggestions . .also getting ready to install the wideband just have to get the bung welded.

What's the logger show for batt volts, when this happens??
Sounds like wiring to me.

i jacked the car up last night to fix the drive shaft loop its hitting the driveshaft when i hit the brakes to slowdown.i will look at it when i get the car down today thanks.let you know even the headlights dim .

Well, you've got some strange stuff going on here, but it's hard to say how bad things are, you gave us absolutely NO information on your setup such as chip, and motor equipment etc.

Take a look at the graph here: On none of the pulls did your MAF do anything other than "table top" at 96.6 gps. !

Now look at the data page at that same time slice. Why is your tranny reporting in Park and 3rd gear at the same time? Your linkage messed up?
At nearly 12# of boost you should have way more than 96 gps of MAF flow.

i just looked at the file i attached its at 13volts if you look at it at about 3300-3400 at 10 lbs of bst. o o2s

i put a after market shifter and i disabled the stock linkage to the tranny is that wrong ?how should i have done ?it the motor is stock the only after market parts are the 60lbs motrons gen 2 with 4''card style maf i have the gen2 set to megamaf also pl 2.2sm 2800 stall gn1 stock streched 60mm tb 3''terryhouston dp internalwg.the chip tt5.7

I also have an aftermarket shifter (B&M streetstick), but kept the stock lingage hooked up so the computer doesn't get confused.

Here's how I did it: Here you can see I mounted the stock linkage on top of the B&M linkage, I didn't like how the nut wasn't quite on as far as I like so if you look REAL close you can see a tiny weld tack that hold the two levers together. It's below the nut and on the back side of the two levers. Very hard to see.
The cable is hooked to the B&M lever, not to the stock lever, but you can see the stock linkage connected that goes up to the steering column collar.

 

[TurboDave]

So you're running a 5.7 chip with the GenII ?? What are your MAF IN and MAF OUT settings in the GenII ??

Could you expand on the computer getting confused. Want to learn. I also have the B&M, however took the old linkage off. Thanks

in is set to4''mega but maf but when i got it i thought it was an ls6 maf so i tried both setting it idle better with the mega settingbut still allittle rough.so maybe i should reset the ecm before each change of the maf i didnt do that maf out is set to gn stock maf.ok so i am going to do that with the linkage just have to get it out of the box of the shifter.i posted pics of the maf

 

[TurboDave]

Well, depending on how certain chips are made there are some things that are different depending on whether the car is in gear or in park/neutral. Probably nothing critical but one never knows

Not familiar with that particular maf. But I'm concerned why your MAF is only hitting 96.6 Should MUCH higher than that for the 11# of boost on that area I highlighted.

 

[bpman1234]

ok gonnago back and reset my ecm because i didnt do that when i went back and fourth between the ls6 setting and the mega setting seenwhat happens .mr dave what should the reading sbe at the maff at idle or it has to be under load to check it properly ?

 

[TurboDave]

At the beginning of your file where the engine is idling, the MAF is reading 10.6 which is WAY higher than I would expect. The norm for a "stock range" (non extender chip) MAF reading at idle should be 5-7 (5-6 is ideal).

 

[bpman1234]

ok going to double check everything at the doctors right now soon as I get home I'll recheck everything thanks.

 

[bpman1234]

ok i'am back with a little up date fixed the shifter the way turbodave showed me in the pic also put the wideband in fix the drive shaft loop .i reset the gen 2 buy [HOLDING DOWN THE RIGHT TOP BOTTON TILL IT SAYS ALL DATA RESET].also reset the ecm. i got the maf in set to 4''maga .it would not idle well with it set to ls6. so i let it idle till it warmed up it it still on stands so no road test yet the wide band guage is reading 7-8 is that normal for gas ?will post logs real soon.thanks

 

[TurboDave]

Do you have the maf out set to match your chip?

The wideband read 7-8?? even after some warmup?? YIKES!! The car should have stunk something terrible if it is running that rich!!! Or if it didn't stink rich, then there's a good chance the wideband has an issue.

 

[bpman1234]

yes it set to stock gn for right now using the tt5.7 till i put in the ext pro chip hers a log in drive way stabbing throttle acouple of times.

everything is new .but the guage .
