Hermie Posted April 25 Share Posted April 25 Hi all Looking for some help with a couple of questions. Some general questions on XR8 and also some PCMtec software qustions. Original setup was running XR8 engine BF2006 with ZF 6speed auto with Standalone Harness and modified PCM, PATS disabled & speed source was set to ABS by wire off memory as the striped down ABS module was still wired in and a speed conversion box was to be wired up to a separate tail shaft speed sensor. somewhere along the build process I had what i thought was a great idea and decided to buy a complete harness with modules out of a 2007 / 08 XR8 ute and incorporate the ABS & ESC and so the fun begins. So long story shortened every thing in including steering column and all seems to be working including the abs has no fault codes. Engine starts, brakes work but of course it's in limp mode, I believe due to speed source! Transmission has 1 fault code on reverse light, BF instro cluster plugged in engine check light on and no speedo working. First Question? does the BF XR8 Instro Cluster receive it's speed source via the ABS via Can or the Trans OSS via Can?? I have tried changing it to Trans OSS and raised the car on the hoist and put it into drive but still no speed reading at the speedo. Second Question? Using Forscan I can see the Trans OSS speed sensor speed and also each ABS wheel sensor speeds but when using PCM Tec via data logger can I view these?? Third Question? how many locations do I need to change in PCM tech to change the Diff ratio to 3.0 and why does the stock show 63.999 but the changed value shows the 2.729 which I believe is the stock Diff ratio for the XR8 Quote Link to comment Share on other sites More sharing options...
