Mk3highline 10 Posted November 19, 2014 Been wondering if it's normal practice to check all sensors and engine health before a remap? I personally would make sure everything from the coolant temp sensor iat maf injectors and lambada were well within spec As if it gets mapped with whatever inaccurate reading from one of the sensors it may affect the quality of the map at a later point?? Just curious I have noted down live reading and check against them every so often just to keep on top of it Wonder how much difference each sensor out by say 10% could make Quote Share this post Link to post Share on other sites

Mk3highline 10 Posted November 19, 2014 I've recently been checking long term fuel trim With the 12v it was on 0 Yesterday with 24v it was on -8.6 with 1600 miles coverd so went out looking for some PEA based injector cleaner Only one I got hold of was the bg44k which I'm sure still got that in I Reset the ecu will see how the fuel trims change to get my injectors out front end and inlet needs to come off Otherwise would get ultrasonic cleaning To Clean piston tops and combustion chamber spray water In the inlet controled obviously I use my water/meth kit Quote Share this post Link to post Share on other sites
