Auto Conversion Idle Help

[mpsteil]

Anyone here do an auto conv and have idle problems. My 110 was converted to auto and it will die at startup somtimes or when you come to a stop sign. I read on ECR's website they mess with the ECU when they do there auto conv but I would not know where to start. Shifting is good and the problem is spuratic(sp?). I dont think the shop who did the job did not hook up the starter inhibit switch or the park safety switch. Any thoughts would help. The problem is not real bad just real annoying. Mike

May not be related, but sounds like the IAC (stepper motor). I wonder if it's not compensating for the bit more of load that always being in gear is putting on the motor.

Michael, Maybe You Should Just Sell It To Me That Will Get Rid Of Your Problem All Together.

I don't think the auto trans and your idle problem are related.

If this was recent work, get in there and check all connections to the stepper, ECU, etc.

Mark, if I sell you my last Land Rover I might have to buy a mini van or a j**p and we all dont want that.

The work is not recent. The PO had the conversion done a few years back and he said the intermittent problem started after the auto was installed. I dont know what a stepper motor is but I will find out and check it. Thanks, Mike

The idle on an automatic is higher to eliminate stalls when turning the torque converter while your foot is on the brake. I would guess that is what is reset in the ECU.

Mike, I will look in the wiring diagrams in the service manual and see if it shows some kind of connection from the shifter to the ECU. I believe the way it is supposed to work is when you put it in gear it raises the idle.

Follow-up Post:

It looks like the Auto Shifter is connected to the Multi Function ECU at C062-3 (BK,0.5).

Do you have any wires connected from the shifter to the harness?

The park/ inhibit switch must be tied into the ECU. If it isn't done it will cause idle flair and such when shifting into Park and a low idle when in gear, like when you are at a stop light.
Hook the truck up to an Auto-Logic or other unit and in the settings you can see a window that indicates the gear. It either will or will not show a difference when the truck is put in gear. In the Auto-Logic it says "Drive" when in R or D and "Park" when in P or N. If you don't see this change that means the ECU still thinks is a 5 speed and its never gonna have 100% at idle or in gear.

Email me if you plan to do the work yourself and I'll tell you what to do to hook it up correctly.
That or take it back to the shop that did the work and tell them to complete the job.

This is the same thing that happens with the new AC systems, like the ones RN sells. The installers don't tie it into the ECU and then you'll get a low idle, or even a stall when the compressor kicks in. Then folks start messing with engine adjustments to try and "cure" it, when the problem was just the ECU not knowing when te AC was on in the first place. :)

Thanks, Mike. I will email you. I am going to try and do it myself. I have access to an Auto logic. I tried the shop who did the work for the PO and they were less than happy to even talk about let alone fix it. I just wish you guys were on the west coast and not so far away.

Thanks again. Mike

If not the stepper, I just read this...(fell under RRC tips, not sure the 90 is the same but it said v8s...)

Michael did this fix your problem? I also have 110 with a poor auto conversion and I have the same issues. The park safety swith especially with little kids and dogs running around is my biggest concern.

[mpsteil]

I have not fixed the problem yet. Mike at ECR pushed me in the right direction but I have not really worked on the truck for awhile. My idle problem would come and go but now it seems it is getting worse so I will have to address it soon. I will post what I come up with once I start playing with it. Mike

Sorry resurrecting a very old thread, but I am having the same issues with my automatic 110. Mike, did anything come of your situation? Thanks in advance!
