I installed my grounding kit and get my MPG to go up to 80 per GALLON!!! I also now pick up radio stations as far away as China and also the car now handles MUCH MUCH better

 

Dude that was uncalled for, he is simply stating the facts of his situation here and you go off basically calling him a ricer. Grow up.

 

If you two don't like what you read here then move on to another thread! No need for you two to act like children and write what you did. Indeed, grow up.

 

I agree with Warrtalon definitely sounds like clutch slippage... My car does the same thing right around when I hit 3300 rpms it just revs up to about 4000rpms and then will catch again so I know my clutch is going out.

 

If you are boosting that high you might be getting a BOV leak. That might be the sound that you are hearing. Or it could be the wastegate. I have a grounding kit and have no trouble like that. Try removing just one leg of the grounding kit at a time and see which leg is the one causing the weird condition. I would guess that the first one (batt to fender) would be the one. You are just improving your cars ground loop which lets the ECU + voltages to signal ground work better.


Lets say your ground has a value of +2 VDC and your boost solenoid is +5 VDC it would only be seeing +3 VDC difference and the ECU would assume that it is only +3 not +5 volts. Now, you install a ground kit and your ground go to +0 and your boost solenoid is +5 your ECU might up your boost to a higher level which might cause the boost to over power your BOV and whoosh boost leak thru the BOV.

similar can happen in reverse. One easy check it to start you car with the ground kit disconnect and take a volt meter reading from the - terminal to a good ground on the fender see what the VDC reading is. anything other than 0 is not good. You might have voltage on your ground and this will cause sensor miss readings and tuning issues.


I AM NOT AND EXPERT! ! ! This is just my $.02 and what I would do to help narrow down the problem.

 

Both of myh previous clutches did the same. WOT in 3rd gear they would slip slightly (on ramp to the freeway) and then grab. That is when you order a new one.



If your RPM's go up and the speedo does not = clutch.

 

humm werid i wonder what it is. hey do you have logging of this with wire off and wire on. if so do that and that will tell you for sure. becasue can be in your head. maybe i will try the ground kit. and see what happens and i will log too. and see what happens will do the same time of day and every thing.

 

......if you install 3 of those you can get into the 11's no problem

 

i'm going to troubleshoot it more this weekend. and do the one wire removal method like Cajun Power said. thanks for y'alls help. i'll let you know what i find out.

 

I put in a grounding kit and it did nothing. Luckily, I made it myself and spend less than $40. I'm not doubting you had a change after the install, but I find it hard to believe it was all caused by a few wires...

 

you are god i went crazy and i got 0 gage wire. so that was like nuts biger then the kit was selling. and you are total right. was runing 11s only down fall is that way to much more weight in front. so i mounted the intercoler in the back on the wing. but now geting to much lag for turbo. but its ok. not runing 11 flat but dong 11.3 which is not bad. so maybe i will just take out all the interoe and the ac and abs and then but the intercoler back in front and will be set.

 

all the kit was made for is to get better signal reading for the car ecu. so throdle and what not is more responvie.
