right I had my 24x motor running no problem.

It didn't have any oil pressure and the cam was all glittery and washed off. So I have a late model gen 4 going back in. Just wanted to make sure I was still cam sensor free (asking Tony Paul)

Mike said he would be able to solder the resistors in before selling it no problem, not sure exactly how much it will be but a rough estimate is only $20.

I think he will also be able to load in one of my tunes if you want

Were you able to target 14.7 at idle and it actually be 14.7 with batch 80s?

I keep clipping min pw as I try to lean it out. I'm hopping when I put the corn in it will work better sense the pw should be up further from the min pw

yeah no problem, with gas or e85 etc, i could lean out the idle till it stalled if i wanted to.

batch does not like to idle lean though, i typically would set it up from 13.0 to 14.0 max

that is where it would pull peak vac and idle smooth

Ok let me know how it turns out. If it all works I'll take one. I don't think one of your tunes would help me out though. I'm on stock injectors right now.

hahaha i have a tune for stock injectors and stock 1 bar map, you can just change the map sensor to 3 bar or whatever you need to, or the stock 1bar. etc

i fired a motor, didnt do any tuning but had it running and idling on stock 28s or 40s, not sure of the size since flex fuel ones are larger, it will be close enough either way.

but i have a tune for stock sized injectors haha

he also said he will label the wires on the harness for ignition outputs, since we repurpose the ALED and WLED wires. he will label spark ABCD instead of what they are.

he is going to mod one and send it to me for testing, i am going to give it the thumbs up and make sure its happy, but i dont see why it would have any trouble if you would want to call him and ask for the same thing

Oh ok. Awesome. I'll take that tune to get me started. I have 24lbs because mine is a non flex fuel motor but it will be closr enough for me. Thanks for your help.

Micro2test bench tune (this fires the car on the stock map sensor, and stock injectors, i dont even know what size and its very rough i didnt even have a wideband when i fired it, but it did run and idle for about 2 minutes, and its all i got, and if you need it you can have it haha.
http://sloppymechanics.com/tunes/Micro2testbench.zip
thats from the first page, where i have the tune file listed for my test bench micro.

that is a stock injector tune that fired and idled. i dont have anymore than that lol

This shows how easy it is to connect and run a lsx engine.

Awesome. So should I just email him and tell him what I want? And did you verify that he could load that bench test tune on it, or should I just do it myself?

I really appreciate all the help you have been

well i sent him my tune files, i also have them up for download.
he said he could load any of my tunes if you guys want em, or you can at home once you get it

i have a 80lb injector turbo cammed 5.3 startup on gasoline and E85
and this bench test motor tune with the stock map 1 bar, and the stock injectors that starts and idles. so that should work great either way

he also changed the labeling in the micro harnesses to say spark ABCD instead of their other purposes
