I have a viper 5901 installed in a 05 Acura RSX type s. I have triple checked everything and as far as i can tell everything is wired and set wright. I have tryed getting the tach signal at the ecu and coil. could not find the test plug behind the driver headlight. I'm stumped.

From what I can tell I have a newer model of the 5901. I guess they changed a few things even though it is still a 5901. I can't find anywere on the brain to chang the tach threshold jumper? It's as if dei did away with it? The install refrence gude dosent talk about ither?

Its been a little awhile since I messed with DEI. Is there anything about programming the tach? If so....did you do that? Also, did you verify that you got the right tach wire with a meter?

Everything is set up right. I have checked everything and read everything over and over .I tried getting the tach at the ecu and a injector. both places read 0-7 volts. This just has me stumped?!
