Hi, I have upgraded my LQ4 to DBW and am having some issues with getting it running. I originally had a 512kb pcm and cable TB and have swapped it out for a 1mb PCM from a 2003 Silverado. I also used the TAC and pedal from the Silverado. With the car sitting there and ignition on the throttle body and pedal position work fine all the way up to 100% so I am thinking the wiring is ok. This setup is in a landcruiser and is also turbo'd so I had to use COS3 as there is no COS5 for the 1mb PCM. I copied all the tables over from the original tune so I was hoping it would start up and run. It dosent unfortunately. It idles very rough and as soon as I tap the throttle it will stall. Could someone please have a look at my tune and see if I have missed something obvious. It is a maffless setup and I have attached a log of it idling also. It now has a LS2 90mm throttle body with X-link converter.
Many thanks
