I'm still going lean. I put in the new rx8 injectors (~350cc). I adjusted the U code vaf to idle about 10:1, and there's less backfire, but there's no avoiding it. It's undriveable unless you find an rpm that doesn't backfire and stay on that rpm. RAWR.
the injectors are probably too big still. Im not sure on proteges but the stock ecu on miatas can only handle 265cc at most without running lean. I have a set of miata tan top injectors, cheap if you want them. 4 wire vtps is awesome and def reccomend getting one.

sooo you're telling me i'm running lean because my injectors are too big? stock gtx injectors are 330ccish-360ccish.
maybe I miss read but you are on the stock ecu? could be not enough pressure at the rail due to bigger injectors using more fuel, ****ty spray due to low pressure can cause funny stuff to happen. ok so gtx ecu, but rx8 injectors are they yellow? if so they are 440s not 350cc. honest opinion. get a 4 wire tps, and a megasquirt, get rid of the vaf and other pains.

gtx ecu. No they're not the 440s. I appreciate your honest opinion.
Not sure what YOU heard, but what I heard was hitting a brick wall!
The car won't crank unless I retard the timing. I can then put it back to 12* and crank it at 12* when it's warm. It's not an easy crank, but it does crank

Before going standalone, are you 100% certain the crank and cam sprockets are dead-on timing? How old is the timing belt and tensioner? When I reassembled my motor I re-used the existing old tensioner, it ran poorly, wouldn't rev past 4500 RPM and struggled to idle at 500-600RPM without some throttle input. The sprockets were lined up correctly when I reassembled everything. When I ripped off the timing assembly the crank was 20° off after 200 miles. New tensioner solved the problem.

Yeah I'm not going standalone any time soon, if ever.
To my knowledge, the timing belt hasn't been replaced. It hasn't hit 60k miles yet [emoji6]
Took all the covers and belts off and my timing hasn't moved.
I still don't know why I'd have turn the distributor to get it to crank.
I'm guessing the base timing must be screwed up. With ten + gnd jumped, the idle is way too low/nonexistent.
Maybe I need to plug up the bp10 ecu, set base timing, and see what happens.
