Viper tuned TCU
Re: Viper tuned TCU
Ajc don't think the old boy would even know how to do that but I could be wrong...can't ask him as he passed away not long after it.

Re: Viper tuned TCU
Atf temp what should it be
Re: Viper tuned TCU
From memory it needs to be above 57 degrees for the box to behave in normal operating conditions.

Re: Viper tuned TCU
Cheers Shopp warming her up now, also how do I check the kick down operation
Re: Viper tuned TCU
61 deg now
Re: Viper tuned TCU
73 deg now so that looks ok
Re: Viper tuned TCU
Up to 80 now
Re: Viper tuned TCU
Can't remember if it's an ECU or a TCU measuring block. Probably TCU. Just have a look through the measuring blocks, it's pretty clearly indicated. When you put your foot down and feel the switch operate, then the input should change to "active" or "on" or something. Obvs, don't do this with the engine running.

Re: Viper tuned TCU
Ok do that tomorrow Shopp just packed everything up. Broke the wire going to the maf putting the air box back on...maf on the right side so just finished soldering it back together, really tight on that right side.
Thanks for your help once again.

Re: Viper tuned TCU
Would the TCU revert too base map if it detected an issue at all? . Almost like a limp mode ? .mind you if should throw up a fault code if this was the case wouldn't it? . Are the input and output seed sensors showing sensible numbers ?

Re: Viper tuned TCU
From my understanding, the MAF data is used as part of the calculation for engine load. If the ECU is talking to the TCU and saying the engine load is actually less that what it is, then could that be a) delivering softer gear changes and b) changing the point at where the TCU changes to 5th?

Re: Viper tuned TCU
How do I check the speed sensors AJ?
Re: Viper tuned TCU
Checked kick down switch, here is a pic,looks ok but not to sure. It says it's ok.

Picture to big I think see if I can resize it
