Now I am going to share with yall , this bit of tuning info that My Buddy Rick Gentry Clued me in on. Most of you may know it already, but thanks for reading this-so here.. When I first setup up my microsquirt, I thought auto tune was the pooh, except this one spot right at idle. Auto tune would always mess it up , and correct over the right settings until it would stall. Then I would have to correct. I showed Rick , and he's all like "ah, no worries , do this.." Select the fuel cells that the computer keeps changing on you ( if it does) like this.




Select -lock selected cells, this means the computer will not mess with these highighted cells at all in autotune, which will help you pinpoint and fine tune exact areas of problem.




Now these cells are locked until you unlock them.




Simply unlock.

More fun. A little tune I did, to bring up boost to rocket off the line. I have some great footage of running two hemis chargers from a stop using this. One had terrible reaction, he slept. He gave up instantly.The other started a car in front of me because he couldnt control his burnout before we even started, so he gave himself a car length. Fine! We both left at same time, he didnt gain a inch. Niether did i. Then i hit second gear and it looked like he hit reverse.lol.Towards the end of video , you cant even see either of them. But its too incriminating... Anyway, heres a video of me bouncing off rev limit to create boost off idle. Lag is not a problem. 9 psi lights up the tires, so I usually launch with a little less, then slowly release the clutch, which creates a bullet out of the barrell type feel as the tires are barely crying for grip as clutch slips, tires grip, then at full release of clutch it feels like the front could lift. But i need a few more moose power to do that. https://youtu.be/TF6HIrQubcg

Jason , the dyno tuner said something about that. I wasnt clear on what he meant either. I have no idea.

I think your req_fuel is too low, so you have high VE values to compensate. Also, the fuel load kpa scales all the way to 500 kpa which is ~58 psi worth of boost on top of the 100 kpa atmospheric presure. My turbo miata running on a ms2 has idle VE numbers are around 50-60. The scaling isn't a big deal, as long as the car has good AFRs, unless you want more boost and need more fuel in part of the map (I think 255 is the largest VE value possible).

Required fuel is 3.9 ms. As far as the kpa, I am using a holley 5 bar map.

low req fuel allows a more finely grained tune (if you need it/want it), as long as you have enough to meet the highest demands. think 255 is the highest value you can use on the ve table.

also, on the siphoning for the alcohol inj, a lot of folks started using solenoids for nozzles installed after the tb that are subject to vacuum. food for thought, wouldn't be much to install some and have them come on with the pump.

My header broke again. https://youtu.be/zPLjqiqS4h0 You may remember,I cut and pasted a big block v8 header to 16v flange. I beat on it for maybe 3 months. The collector broke where the 4 merge into one. Not my weld, but for sure my problem. Going to get one made with sch 10 ss by a pro. Just got the flange from Australia. Car did great moving stuff to new house and garage , even though manifold was busted. Still unpacking and arranging stuff. Seems it will never end....

I had this issue on my car with it siphoning the alcohol tank, got a snow performance check valve and that seems to have solved my issues for the moment

Back to the locking of the idle cells deal.

Otto Tune changes the idle cells because it is trying to match the AFR target shown in your AFR table.

When you get the idle right in the VE manually tuning, note the afr's and correct the afr table.

Another aspect of this, is if the AFR table is not corrected and O2 correction is enabled it will do the same to the idle area.

The AFR table needs to reflect exactly what the motor wants, not some magical 14.7 number that few (if any) motors will idle at.

Good to know Cosbysweater. I bought two check valves from devils own, but they both dont work very well at all. I just moved my two jets before tb but after bov and its been doing well ever since.
Dirty Rick, that very well could have been the case . Havent had that issue since, so i probably mucked up the target idle af for a minute, then fixed it.
Manifold flange came in from australia. Two to three weeks out for it to be completed. Turbo still out the hood, but twin on3 wastegates now and true paired pulse manifold for split port hx52. I am kinda excited. Patient pantzzzz

Great stuff buddy! Love it!

One thingi would suggest video wise is to get some kinda aux light and not use your camera/prone light, so you can properly see the stuff on the laptop ;)

Time to put up or shut up. Looks like I may have the current most powerful surviving combo in the states. After my 404 wheel dyno I did some upgrades. Below are pictyres and a video.
