Ok so my gsr with p73 pistons is running weird lean. What i mean by weird is. Number one spark plug is tan. Nuber 2 is tan but shows white and 3 is whiteish tan and 4 is white. Will post pics once i get home from work. I tink my injectors need to be cleaned out. What do u guys tink. Also i had a compresion of 235ish all acros the board when the build was finished and it had 1k miles on it. Now its like barely 200 across the board. My timing was off (+/- 26*) so it was runing rich. Could this have washed out my rings. I noticed the plugs get white right after i set my timing to specs. Will perform a leak down test.

 

what ecu are you running ?

 

Sorry for the long reply.
Im running a stock gsr p72 ecu for now untill i get a chipped p28 etc etc
Any ideas on why it would run perfect in cyll # 1 and the rest are whiteish collor

 

that could be your problem...running the wrong ecu

 

Ok
So what ecu would u sugest me to run at an minimal cost that will plug and play.

 

p28 chipped with an itr basemap...or just get an itr ecu. with the p28 you'll need to get an obd2a to obd1 jumper harness. with the itr ecu it'll just plug and play but i highly recommend the p28 for a few extra bucks..

 

How much will an itr ecu run me about. The p28 chipped ecu is an expencive thing. Im loking to do the plug and play way with an itr ecu. Wich itr ecu shuld i get. I know it has to be obd2. But does it matter what year.

 

your is a 97 gsr so i would get the 97 or 98 itr ecu and it should run you about $130-$150, maybe cheaper if your lucky

 

WTH
If someone was selling an itr ecu in my area for that much id be not here but instaling it lol. Im getting an obd1 gsr ecu thats chipped with an convesion harnes with an basemap to run my car till i get all the good stuff then get a good street tune.

 

just look for one online...they're everywhere

 

The closest one to me is in hollywood la....wich is an 6 7 hour drive..?

 

i have a 94 gsr with 1.8l lsvtec swap and modified gsr intake. so its all back like it was with the gsr. i have 9.2/1 comp je pistons. with stock fuel and skunk 2 pro 1 cams what ecu should i be using

 

Tread jack much there...lol
