just an fyi, 830cc/min injectors are too large to use with the maft on the 7m. ecu just cant pull enough duty cycle under 200hz of airflow for it to run properly. over that car runs great. im going to get an adj fpr and lower the base pressure 5psi or so to lower the injectors flow. friend of mine is using 780's with success on a lex safc combo. so fuel flow doesnt need lowered much.

knock was fine. numbers were normal under the conditions. highest it went was in the 40's on the afc. audible detonation is far far above that. think it was ~300 when i had det and blew my 2mm mhg. anyhow. the base timing is still at 10deg, and ill be going standalone soon anyway. just wanted to get them in and see how it ran. i think itll do ok once i get an adj fpr in there. i have 2 cars so dont need to drive it right now. my 85 gets much much better gas mileage. gonna start putting the new engine for it together soon anyway.

dont know about soon, but it wont be too long hopefully. lots of stuff left to buy and going all out the right way, costs alot, but ill get there eventually. problem is im building 2 diff mkii's at the same time. kinda slows things down.
