In the DDEC 11 book the J3 wire does the same in DDEC 11, 111, & 1V. It is as Jim says the PWM #1 output. It is the wire that lets the ECU on the engine talk to the ECU on the transmission. It is connected to the "throttle interface module". This is a module that takes the place of having two throttles. The tranny requires a throttle and the engine requires a throttle as well. This module is not supplied by DD as far as I know. I got mine from a company in Hibbing MN called DMR Electronics Inc.
In the book it also says that if the throttle will not operate properly and no codes it could indicate that the throttle module is out of range. It needs to be adjusted. Some have a slotted screw holes and the newer ones don't. You have to replace them. Hope you can get some help from the info. Bill |

thanks bill
i spoke to mitchells diesels here in the uk and the allinson specialist didnt think that this is the problem with our racetruck ,he thinks it could be turbo lag so we are going to fool a few sensors and see what happens .the problem we have is if you floor the accelerator it takes around 5 secs for the engine to pick up ,yet if you do the cylinder dropout test at 1000 rpm the engine picks up instantly, as a race truck this is what we want .when you go into ddr readings it tells us this engine is rated at 1100 bp .i have checked all the sensors out and they seem ok ,i will carry on trying to find this problem with all your help .
many thanks keith d dyson
