anybody who ever owned an ST170 will more than likely have come across this 1508 issue.. faulty imrc.. mine occurred just 5 weeks ago, i already had carried out some mods as this is a high days and track car so my engine bay is less cluttered than stock, and i had repositioned the IMRC box to above the left engine mount.. easy to remove and its being repaired at present faulty transistor inside the box.. so its off the car.. i'm a cycle guy as well as a gear head so i thought to use an old bike downtube gear lever with cable and wire [Shimano Positron] to pull the manifold lever forward where it would be after start up on any st170 .. this i did, its perhaps 7/8 of the full travel forward and car revs better to the cut out than before and gets to illegal mph with more torque faster than ever.. i know that this system is to my mind designed the wrong way around , i would have it set to pull after 5k to get to the short runners.. not the way it is in Fords std vehicles.. has anyone else played around with these settings..i don't know if i will refit it after its fixed..

 

a mate of mine in the states with a svt has various settings on his imrc so I know it can be done

 

thanks for your input, perhaps some of the kit car 7 types would have tried this, i know they like the st170 unit.. ANYBODY out there??

 

Ive been having problems with mine too. Do you have any pics of where you have relocated the imcr.

 

Glenn as I have a modded left side of underbonnet with no air box, no battery no air box brackets which bolt on the left engine trans mount and a trunked out cold air supply from the throttle body right down to behind the valence i was able to use a one bolt connection just about where the resonater part of the air filter housing would sit.. cable sits nicely in a broad loop .. my camera and windows 10 don't get along so bear with me and i'll try again for some pics.. as i said above i doubt if i'll fit it again.. i'll pull the EML bulb before next feb's MOT..

 

Ok cool matey. There isnt much room under the bonnet of the st.
