car: 93 integra auto to 5spd converted
Specs: b20 block with a b18a1 auto head. 450cc Injectors DSM. 255 fuel pump
My question is it has a stock auto ecu and car is running rich, rough idle untill warm and I was wondering which ecu/tune to use

 

obd1 or obd2?

 

Obd1

 

obd1 tune it to 5 speed capabilities, auto will hold you back alot.

 

If I get a stock p28 will I notice any difference? Or would it still run the same ...

 

are you using stock ecu to run dsm injector? a tune will solve alot of your issue. find a good tunner to tune!!

 

The p28 is made to run the D16z6, which is sohc.

You have a 2.0, which is DOHC. Will not work without being chipped. If I were you, look up phearable or Xenecron tuning, they both have a website. Go there, and read.

You will need to socket your ecu, and get a basemap for a b20. Also, no need to have 450cc injectors on an otherwise stock setup.

 

Sorry forgot to add that it is turbo and a non v

 

what island you from??
