honestly if a shop doesn't have the fsm and is going to take your motor apart, go somewhere else because that is a really bad sign. It sounds like they screwed up the initial install and tried to operate the vehicle with the parts and sensors out of alignment which has resulted in other parts failing, such as setting the position sensors wrong enough that the vvel actuator was trying to turn through the stop overloading the servo drive in the control module and possibly leading to an over current situation on one bank that has damaged the sensors and wiring (each VVEL actuator can pull 40 amps at full dead load on the stops enough that you can see a witness mark from the torque on the shaft when it goes to the stop on the head). Most shops that reuse the vvel actuators on a built engine either mark the position of the actuator link and the control sensor before removal which will get it close enough to run without codes when fired back up, or perform the reset from the minimum lift position which leads to a 5 degree error in actual control shaft position but usually works. If you have a set of the factory actuator position keepers from a pair of new vvel actuators, or use a digital angle gauge you can actually perform the factory reset per the manual while reusing the old actuators and get factory accuracy on the control shaft position. I outlined the process in other thread.

Any Dyno numbers with these cams yet?
|
well I made a two **** tons of power with them but you can't really use me as an example because there is nothing stock under my hood really.

everything attached to the heads is custom plus drysump and other stuff.

Nice yo,bet that dry sump helps keep the oil temp down too huh?

Guys Finally,
The car is up running. The problem is fixed and the car will be on the dyno tomorrow. I will send the sheet for you guys to see and get your feedback. Thanks for all who supported me :) |

Glad it finally got put together correctly for you.
|
Can you please share what exactly the problem was and how it was fixed? It may help anyone else facing similar issues
|
sooo.... whats going on?
|
I'm with this guy

Old thread bump..i'm having hell with p1090 and the passenger side vvel motor. I even replaced the engine and problem remains. Relay has been replaced. Followed FSM and tested continuity from vvel motor to the actual vvel controler and fine no issues. Tested ohms on vvel motor and good. Replaced the relay and same problem. Replaced the VVEL distributor module this morning and same issue. Literally stumped. OP never stated how he fixed his
|
*Update for completeness sake: After replacing the VVEL control module i disregarded the programming section. This had to be done for me. I used uprev to data log to voltage for the position sensors on the back of the vvel modules and adjusted them back into the required 5v range as stated by FSM. Issue seems to be resolved.
