My Escort LX BPTed

ehhhh....

the NA computer runs too much timing advance at high rpm in boost, which can melt pistons and bend rods. not to mention someone also dynoed with it and found that it also tended to lean out at high rpms.... it runs wicked rich during cruise though so your gas mileage sucks.

your best bet is to get a GTX ecu for like $200.

The timing part I can agree with. GTX ecu i dont like due to the low rev limiter in 1st gear. And fuel cut issues.

rev limiter? all me gears have the same rev limits.....

Anyway, my first gear spins too much so I need to shift in second anyway

its not 300 rpm that will do a difference

Quotes from the link:

The problem is that there is noticeable power loss. With the NA ecu I can light up the tires in 3rd, can't with the GTX ecu.

Conclusions - the NA runs very rich while cruising and leans out dangerously at high RPMS. It also has significantly more power, presumably from more aggressive timing.
The GTX gets much better gas mileage and is safer for your engine because it has a proper A/F curve.
