So I've been running a b20 with stock tb and sk2 intake with a phearable tun, I just recently put on a professional products 65mm tb and when I use any more then half throttle I throw a cel

I can make it to red line in every gear using half throttle now

Do I need to get it retuned or is my tps or map not reading properly

I can't pull the cel becase it goes away as soon as I turn the car off and putting a jumpper in there while its running doesn't do anything

 

Lessee. Installs component that changes the amount of air introduced into the system. Wonders if he needs a retune.

 

did you calibrate the tps when you put it in?

 

^^That would to it.

 

Good call

 

So here's the update

Got it tuned
New o2 sensor
Calibrated the tsp
Changed the map sensor

In 3rd gear when I go over 5k I throw a cel, only if I use more than 3/4 throttle

Cel goes away when car is turned off and back on
Jumpping while car and cel is on does not work

 

See if you can borrow an ecu and try to jump the code if it comes on. Sounds like an ecu issue.

 

i drove my friends 93 4dr yesterday and he has a d16z6 in the car, i gave it full throttle from 2nd to 4th and while i was in 3rd gear at high rpms his cel light came on

doing the same thing as mine, i turned his car off and back on, cel went away
only at full throttle at high rpms does it seem to do this

his setup is stock thru and thru, when the cel goes on it feels like both cars have lost power and it takes longer to accelerate

 

2 cars 1 ecu, hmmm you found your problem. /thread

 

2 cars 2 ecus

1 car is b series, phearable tuned ecu
1 car is bone stock d series, stock ecu
