pcm tune
pcm tune wheres the best place to have my pcm tuned in columbus ohio? o and also need to know how to do the wires to my gauges. like oil pressure, tach, speedo, battery, temp. i was reading a swap guide on third gen and they didnt say they were using the plugs on theirs. any help would b appreciated. thanks
Read the sticky on TGO. It well covers them
Oil reuses the late model 3rd gen connector or the 4th gen unit. LSx oil sender works fine
Directly connect the tach to the PCM tach output wire and calibrate the PCM for 6 or 8 cyl operation depending on the cluster
Speedo is a direct connection from the PCM
Voltage meter is read off the overall system charge. No changes are required for this to function
Several options for temp. Modify the 3rd gen sensor to fit the LSx heads, drill/tap the LSx head for the 3rd gen sensor, or use a 98 Fbody temp sender combining the CTS and temp sender into one sensor. The 98 sender uses the same connector type as a TPS
