Need some Tach/speedo help
hey guys, it's been forever since i posted over here but ive just finished up a 2.3 turbo swap and have a couple issues..
the truck is a 1996, originally a 4.0
it now has a 2.3 turbo in it, the ecu is from a 98 (code flh2), the engine harness is from a 98 as well, the trans harness is from a 96. lots of 96 guys use the 98 ecu without any of these issues so i do not think that's the problem
The stock gauge cluster is in the truck (tach/speedo) and currently the tach reads low and the speedo does not work.
does anyone have suggestions on what to check?
1996 - 10:1 CR 4.0, P&P 98TM heads, 422 Cam, BBK 66mm TB, FMS 30-lbs Injectors -3.73 & Trac Loc - Caltrac Bars - 5sp swap/HURST - SN95 rear brakes, 12" sport trac front brakes - DJM 4/5 - Rear air shocks - Lots more
