HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Hi all,

New to the forum. Lots of great information here. Driving an 86 951 with LT1 for 3yrs now. Conversion done by PO. The harness used by the PO does not have an OBD port. Engine is a 97 so should have been OBD2. Has anyone here added one to their harness after the fact? I would like to do some diagnostics because it is running really rich and I also did a heads/cam swap a year ago and would like to further adjust the mail order tune I am running now. Thanks in advance for any help you can give.

Post up what the motor came out of and we can give you the wiring colors and locations to hook the data plug to. The wires are probably still there, I don't know why people do that. Every body needs a data plug.................... Shocked

Thanks for the suggestions. The shbox site has a wealth of good info. Found the relevant connectors but they were partially cut so plan to splice in near the PCM. Looks like just 4 wires to the port. 12v, ground, and 2 data.

Spliced in the port, bought a cable, and downloaded Datamaster. Shows DTC 43 - knock sensor circuit. Looks like I have an OBD2 sensor (1997 donor engine) but an OBD1 pcm. This incompatibility causes DTC 43 which then pulls lots of timing and richens a/f n an attempt to supress knock without any data - almost a "limp home" mode. I guess that explains why my car felt slow for my mods - and the cat melted. Very convenient since the car turns 25 years old in 3 weeks and will be emissions exempt in WA. Ordered up a new sensor, can't wait to see what I've been missing....
