HEY all just wanted to know if it was smart to do that i would like to have it tunred to about 15 to 16 psi and then when i get my wide band ill fine tune it

 

NO, NO, NO! NOT SMART!

I wouldn't trust XS to tune a guitar, let alone my car. And forget a mail-order tune from them.

Mail order tunes do NOT work, in general. You can get a safe map from the rx7store, but it's just a starting point.

You have a T-78, get a real tune. I know there is at least one good tuner in your area and then there is Steve Kan, of course.

 

hehe. well, that is debatable...

there are a couple of good tuners in your area. i think demetrious is one of them. i think his screen name is rotor_dee or something like that. try pm'ing rxrotary2_7 for some info as well.

 

I've heard bad things about XS. Sending them your ecu would be high on my list of things not to do.

 

Yea, Don't do it. Waste of money. You could take it to a dyno with WB02 and see how close you are on AFR but dynos sometimes are dangerous for poorly tuned rotaries. Pay a tuner or get a Datalogit and WBO2 setup.
