You can disconnect the cable after the engine is started. ----- Original Message ----- From: Eric McCord To: Ray Ayala Cc: [email protected] Sent: Sunday, May 31, 2009 11:02 AM Subject: Re: Link display issue and going into limp mode @4k rpm
I checked the air temp sensor to ground and it is good. I also checked across the pins on the coolant temp sensor and it is not open. I don't see any shorted wires. I unfortunately have the Link set to not start without the keypad so trying it with the cable disconnected at the ECU is not possible.

The limp-home mode can be caused by a high coolant temp signal (a shorted wire will do this) or a missing air temp signal (wire either shorted or open). The display cables are known to go bad over time just because the plastic insulation hardens and cracks, even if they are not being used. I'd suggest disconnecting the cable from the ECU ... at the ECU end ... If one of the display cable wires is shorted to something it also can also produce unpredictable symptoms. ----- Original Message ----- From: Eric McCord To: Ray Ayala Cc: [email protected] Sent: Sunday, May 31, 2009 9:16 AM Subject: Re: Link display issue and going into limp mode @4k rpm All the grounds are connected, no pinched wire. Still no text display on the Link keypad. Eric On Sat, May 30, 2009 at 9:07 PM, Ray Ayala <[email protected]> wrote: Check to be sure all of the grounds got reconnected. If that's not it, follow all of the wiring harnesses around the engine bay and look for possible pinched wiring. ----- Original Message ----- From: Eric McCord To: [email protected] Sent: Saturday, May 30, 2009 6:02 PM Subject: Link display issue and going into limp mode @4k rpm I just completed a headgasket change and coolant reroute. I now have no display on the link pad but the buttons light up and the backlight comes on. Also I hit what feels like the limp home mode but it varies between 3k and 4k. I can build boost in 3rd gear up to 5psi but when I hit 4k it hits the limp home mode.
