The guy he's buying it from has the ECU tuned for everything on there right now. which is good. but he recently put in a 90mm?? MAF sensor, but didn't tune for it. he says it still drives fine but up around 6k rpms it starts to lean out and won't accelerate as quickly. he wants to know:
1. is it safe to race like that?
2. is it safe to drive on the street(not racing)
3. does he absolutely need a tune as soon as he is able to?

heres some pics of the car.







bump

 

hahahahahahahahahahahah, tell him to fix the hood, please.

 

yeah he'll be making his own touches. but he needs to figure out the tune first

 

morning bump

 

I hope the rest of the install isn't as ghetto as that hood....

probably not safe to race if it leans out, usually when your lean you tend to knock. To be safe I'd have the sensor tuned before any racing is done.

 

normal driving hes fine. racing is a get that thing richened up and then carry on

 

alright guys, thanks for the input. unlike other people

 

ah ****. i know that car.

 

Not a bad idea the builder had there. If the rest of the install isn't shoddy then that car could really be ***** to the wall.

 

he said its in ottowa or something KS

 

a friend of mine bought it here in kc. then sold it.

meh...

 

is it any good? he used to have a 4dr LT cobalt but some made a left in front of him at the light and he t boned them and totalled it.

 

You need to get a retune for it asap. If the car is not tuned for the 90mm MAF then the tune is off from idle.


As for everyone making fun of the hood, if you've ever seen a Lightning motor its huge. Its pretty hard to find a colw hood that big.

The car should run pretty good with that motor, I think that should be a 12sec car easily.

 

i assume if hes got closed loop enabled he can drive in closed loop (part throttle to idle) otherwise the bigger maf could drastically underestimate the airflow and depending on how close the original tune was to the knock threshold he might either be fucked or fine everytime he goes WOT

 

Just install the OEM MAF and fix the problem....
