have with the colour code for the wires the gauge come with. My sunpro a/f gauge has 4 wires red - power, black - ground, green - signal from o2 sensor & white - illumination. I got my instruction manual by using Google to find the brand gauge i have.Last edited by mazkam; 09-04-2010, 09:06 AM.

Narrowband is pretty much just a bouncing light show. -completely worthless for tuning."See that car, in the 80's that car was deadly." Random man to his son while passing the GTX in a parking lot

i started to pull the starter on one of the gtx's. got frustrated with the heat and starter location, then gave up on it for a few beers.... plus a buddy's kids b-day party was going down. ehh.
edit: i didnt want to post again, since it was just me again... lol
1) started the GTX. after a little messaging, it fired up for me. however, it has some major tapping issue at first. sounded almost like a rod. but it clean up after a few seconds, figured it was the valve train after sitting for the last 3 years. seems as if there isnt enough oil pressure, cause the tapping only slight went away. dont think its rod knock. going to swap out the oil pump, see if that clears it. chassis lists 250k+ miles and its seen a few rallies in southern california.
2) i swapped out the new CA approved cat for a fully gutted cat. doesnt sound that much different in the cab, but outside is another story. under spool, you can CLEARLY hear the turbo from about 20 ft away. nothing crazy noisy, just the whirl sound of a turbo. according to my buddy, riding 20 ft behind in his truck, sort of sounds like an angry srt4 just less dB. idk what he meant by that though. lol
edit #2: checked gas mileage on the GT.. it averaged (more city & less freeway) 21.4 MPG .. thought for sure it was more. bit of a shocker considering every honda i have had was in the 35+ range city only on 87!Last edited by 99EJ6T; 09-11-2010, 12:52 AM.88 GT - DD
88 GTX - whore
