hotwire 352 Report post Posted August 25, 2006 Can anybody confirm as to being able to change tacho calibration between 4 & 6 cylinders & vice versa in the E30 cluster(without mods to or changing tacho) eg some form of switching mechanism?

Gus 5 Report post Posted August 25, 2006 probably easier just to swap the whole 6cyl tacho in...should be cheap Quote Share this post Link to post Share on other sites
gmccormack 0 Report post Posted August 26, 2006 The instrument clusters were fitted with a coding plug in 86. It's a 10 x 20mm plastic rectange with two clips holding it in to the back of the cluster assembly. Fit a 6 cylinder plug to your 4 cylinder tach and it should read correctly. If your car is pre 86 it's easier to swap the whole cluster Quote Share this post Link to post Share on other sites

If your car is pre 86 it's easier to swap the whole cluster Thanks for the info, thought that may be the case, but can you confirm that coding plug you mention as fitted in the front bottom right of the dash (below the idiot lights & sitting behind the lower part of the fascia trim? This dash has the plug you describe fitted there rather than in the back of the cluster. Cheers Grant Edited August 26, 2006 by hotwire Quote Share this post Link to post Share on other sites
