Title: ECU Remap
Post by: daved on March 17, 2012, 10:23:29 PM

Im having a serious think about getting an ecu remap. maybe one of these:

any comments or experience of similar ?

cheers

why ? your jeep aint a race car, got loads of power for off road use ???

I know where youre coming from but you can never have too much grunt for towing and with both "driving sensibly" you can get better mpg.

I know itll take a lot of miles to recoup the cost but I can enjoy better towing.......................I hope  :icon_biggrin:

This. I used to run a jetchip. Similar deal to what you're looking at. Waste of time, Imo.

They think the JK CRD is a V6. Obviously experts. :wsmile:

what you need to reasearch is have jeep restricted power across the engine range for the same size lump. ie a lower spec has less power than a higher spec of the same engine. if that is the case then it should be simple to remap the ecu to allow full throttle etc as intended.

example.

for those people who bought the "new" mini cooper the engine allows 90% throttle travel which is limited by the ecu. the mini one has exactly the same engine but the throttle travel is restricted to 60% hence the power output being lower. remapping the ecu allows the throttle to open to the same as the cooper variant. The car prices between the two models is more than the remap plus if you debadge the car you cant tell unless your aware of the trim specs.

be wary of remapping companies that just increase the fueling etc to get more power, personally i would ask to see the emmissions details pre and post as there should bit little difference.

My personal view is that it's not worth it for a 4x4 the torque levels and power output are set at that level for a reason, practicality.
