air/fuel

hey, well putting the turbo on my car was a huge success! thanks for all your help guys! i was just wondering something, i am going to get both an air/ fuel guage and a boost guage,

now i was told the air fuel guage connects to the 02 sensor and power and ground??? well i looked at the wires coming out of the hasrness before the o2 sensor and there were like four or five wires?? which one to i tap into?? if you guys know that would help out alot...

also just to make sure, does the boost guage vaccuum line connect to the line that goes to the wastegate?? or is their a different line it connects to??

thanks again for all your help!

1. You probably have that small as hell nylon hose, and I have no idea what fitting to tap it into a hose with. You'll need to find a T fitting where the stock rubber hose can run through it, and the T part has an NPT fitting (I assume that's what you have) for you to use the little pieces to connect it with. If you decide to go the easy way, scrap that small hose and just get some rubber hose to put over the end of the boost gauge fitting. Like this: http://www.roadraceengineering.com/...nstructions.htm

2. A/F gauges are useless and a waste of money on a stock o2 sensor, but if you have a gauge, here you go: http://www.dsmtuners.com/forums/showthread.php?t=69282


I had the same problems when I was installing my gauges. You don't tap the wire AT the o2 sensor...you tap into the o2 pin wire on the ECU. You tap the boost gauge vac-line into the left hose coming out of the intake manifold...it should be evident from the pics in the RRE tutorial. Good luck, post here again or pm me if you have problems.

Wait is this a r/gs or a gst/x

right on, i'll check it out tomarrow! with the air fuel guage you are talking about the wire that comes directly out of the o2 sensor right?

also i have the 420a engine would i still be able to put the boost guage to where you said or is their some other place? you have the 4g63 engine so i think the throttle body is different? i don't think that i can splice into the hose coming out of the turbo to the wastegate because it would only read to the set boost i put the turbo at right?

thanks again
