X model ECU into GTX LTD
If i install an X model ECU into my 08 GTX LTD
I should then be able to safely run an xcharger+external IC+42s without running a RRFPR and AFR monitor...
Technically the fueling at idle should be better as well because its actually programmed for 42s
Am i right?

Theorhetically yes! Pulse width is different but not by much. Engine is built to the same tolerances. Should work if you can get it to start.

My question is... why would you wanna swap ecu's in the first place. I'm running a Mini Rude with 48's and stock ecu and have a stock ecu. Does the x ecu have a higher rev limiter by chance?

Just different fuel mapping eg compatible out of the box with external intercooler/xcharger
Theoretically should be cleaner at lower revs because its calibrated for 42s instead of 38s
Plus looks like it would be cheaper than RRFPR (normal diy rrfpr does not appear possible on 08+) and wideband

DIY rrfpr works fine on 08s.

I did this on a 07 rxp and it worked out great. The acceleration difference was night and day. Forget regulators,afr gauges and just ride. Don't forget you need the 42lb injectors. And you lose 150 rpms with the x set up
