very valid point

 

dont just jump in and start cutting ur wiring harness, id say wait but im sure you know already.

 

Oh, I see. I agree. That's why I was asking if they thought the Tuning Shop could do it. I'm not even cutting wires to install my gauges!!! I'm having the shop do the gauges and the oil pan. I'll do everything else. I dont' like messing with electricity.

 

shop labor is to expensive

 

Their really cool their. They told me the front sway bar is a 6 hour job, but they would do it for my buddy (did mine myself ) for $250!!! Every where else quoted me $600!

Installed and tuned one today. After an hour or so of fooling around with it I got a pretty good handle on getting the correct fuel corrections. After the tuning session was all said and done, the car picked up 37.5whp and 27torque Totalling 285whp and 300.7 TQ.(Uncorrected). It is a Turbonetics kit running a Unichip and APEX-i NEO. A bonus with this FIC is that the car can be adjusted to idle a bit richer making it much smoother. (something the owner has disliked about the car since it was new)

 

niceee let's see what paul can do.

 

i almost want to sell my ultimate to get this bad boy

 

This is a question/comment to DelSolid
I had a local shop instll the FIC yesterday and after it was tuned and complete all was good except once in awhile my afr's would go rich for no reason, meaning we did not make a change and then we would make another run and the problem would go away.
Now this morning on my way to work my AFr's were rich (in the 10's) and beyond (below 10.0) and the car stumbled badly and did not fix itself like on the dyno. Any ideas?

 

have you cleaned your maf latley?

 

no but will that that make a difference since the FIC tunes off of the MAP sensor?

 

yes. your cars ecu will still run off your maf. try unpluging your maf and see what happenes. your car wont like it.

 

On my lunch break I'll go buy a can of MAF cleaner and see if that helps.

 

all you need is a little squirt. dont drowned the ****. :D

 

thanks, do I need to let it dry before starting the car?

 

also if you are just crusing at normal speed, and your car goes rich. it ma just be a random missfire. check your plugs too. they may need to be re-gaped.

 

At normal speed AFR is good, only when bossting does it go rich

 

then i would say that the problem most likley is somwhere in the ignition system.

 

Check your long term fuel trim... it may have changed since you were on the dyno and this would change your open loop (aka WOT) tune.

 

Could this be just the ECU making corrections? Is this problem happening the day after your tune or daysss after your tune? The ECU seems like it takes a while to learn
