does anyone know how to get a replacement ECU to rork without taking it to ford to get ripped off ( they want $80 for what they admitted will take all of 5 minutes that equals $960 an hour i'm in the wrong game)? i am puting an XR ECU in my SR but need to get the BEM to talk to it tried the learn mode from the manual where you leave it on for upto 61 minutes to relearn but no luck any help would be appreciated

Going by the sounds of it you have a Smart Sheild vehicle.
Find a mechanic who has an up to date scan tool and he should be able to do. The aftermarket have been able to do the "handshake" as they call it for a couple of years now. I am sorry to inform you that it will not take "5 minutes". Whether they like it or not it will take a minimum of twenty minutes to half an hour. Having said that $80 is about right when you think that dealerships and most workshops have a minimum charge for any work done. This is usually half a hours labour. |

$80 is not unreasonable.

This is a 4.0L i6 right?
Bear in mind, the XR6 had a higher pressure fuel reg than non-XR's. If you where to swap in an XR6 ECU without also adding the XR6 fuel reg, then you will run lean....this is bad.

Engine at idle I6 pressure is 225kpa, I6HO pressure is 250kpa.
Engine off I6 275kpa, I6HO 300kpa. |

GlennBA did this to his old AU and hit problems with the fuel regulator,solution was to get an XR fuel rail.

i thought your AFR's were determend by the o2 sensor? spark/timing maps though???????

the afr's are controlled by the ecu through the o2 sensor, but think about it, a forte ecu has been programmed to run an injector pulse based on a 2.7 bar fuel reg, pump 3.5 bar into it and even if it's running the injectors as short pulsed as possible, it's not allowing for the extra pressure...if that makes sense

e.g. if it calculates there is 100g of air, and the targeted AFR is 10:1, then it will open the injector long enough to give 10g of fuel . When in closed loop, feedback from the O2 sensor is used to check how close the actual AFR is to the targeted AFR. The result of this feedback is stored in a table that is then used to "correct" future pulsewidth calculations for that load x rpm site. BUT, not all rpm x load sites are ever used during closed loop running AND the O2 sensor is only narrowband, so it only really knows how close to stoich the mixture was. So how accurate is it to correct a WOT fuel calculation by X percent, because X was the correction required at idle/cruise? So the "self-learning" component of the EEC is pretty crude when it comes to correcting many parts of the fuel table used during open loop. It appears as though it was really designed just to make sure the car is running as close as possible to stoich during cruise conditions to keep emissions as low as possible.... The other thing to know, is that corrections do not have to be made at all load sites. There is another table that can be used to switch on/off fuel trims being applied at some or all parts of the fuel table. I'm not sure I understand it completely enough to explain it very clearly, so I hope the above helps more than it confuses :P There is some great material on the EEC Tuner, and twEECer forums on the internet. Not to mention the GUFB and CRAI8 strategy documents that where released to the internet a few years ago....well worth a read if your interested.

So you've fitted an XR6 ecu to a non-XR6, and you still have the std non-XR6 fuel pressure regulator?

I actualy thought it was the fuel pump itself that pumped a higher capacity on the xr vs the forte

So if your existing fuel pump was already flowing enough, but you then put a bigger one in, all that extra flow capacity would bypass the reg and go straight back into the fuel tank.
