Fresh MS3X install, set my timing. idle issue? (datalog included)
 

So I followed the manual all the way up until I set my timing. Using fixed advance, and trigger angle I got the timing to be set correctly. The car was idling at 850. When I would give it some gas however, it would sputter and take a second for the rpms to rise. I noticed that my MTX-L gauge was reading 22 the whole time. The car has been sitting for a couple of months in my driveway since the AFR install, should I re-calibrate it or am I running rich and that could be what's causing my idle stutter?

Can someone take a look at my data log and help me figure out this issue? Thanks! I'm so close to test driving my car since I installed the ECU.

I took a second data log playing with the REQFUEL. I had it set at 12.1. The second data log shows the REQFUEL back at default at 11.4, the idle stutter seems worse at 11.4. Also the AFRs are super rich the whole time.

22 is maxing the gauge out. Lean. Not rich.

Basically no fuel.

The log says 7.8 and 7.9. Which is probably an error.

I rose the REQFUEL all the way to 25. The car felt like it improved on both idle and power, but it still doesn't feel like enough power in the higher RPM's. The gauge never left 22.4. Tunerstudio read 7.8/ 7.9 the whole time.

Here is a datalog of drives around the block. With each REQFUEL increase by 1, I drove around the block. I did this from 12-21 then I skipped to 25.

Would I need to change my VE tables for stock injectors?

the file is 5.28mb so I uploaded my new data log to my google drive:

It's broken

Yes. Its called tuning.

The gauge was working fine when I installed it 2 months ago. It's brand new. The car sat in my driveway. I got the tune to function enough to allow me to get the timing set and the car to move.That's why I asked if I should re-calibrate it, I have no experience with these kinds of things, or knowledge on when or how often I should re-calibrate it. I really don't understand how the gauge could be broken.

Oh, I'm familiar with the term thanks, which is why I am in the tuning section of the forums, requesting help in an endeavor that I have no experience in.

After searching I have found that I should be running the reqfuel at 13.2. However this doesn't solve the stutter problem. I would imagine it has something to do with the VE tables. Any help on what to do next would be greatly appreciated. I'm in the manual in section 3.4.1.1 where it discusses the AFR table and VE tables, is raising the fuel percentages something I have to do or can VE analyze live do it? I'm pretty lost here and could really use the help. Thanks.

it won't hurt to recalibrate. give it a shot and see what happens. I doubt the gauge itself it broken.

edit: also, I assume you have already autotuned?

I'll definitely re-calibrate it. I have not. I got a tune from Braineack, and then I've been following the manual step by step, and I'm in section 3.4. I saved a copy of the tune with where I'm at, and I was going to start adjusting fuel percentages in the fuel tables one by one. I didn't know if this was the proper procedure, or if there are catastrophic mistakes that could be made by someone who had no clue with what he was doing lol.

Braniack sent u a base tune. U don't have to manually adjust. Did u get the free or paid version of tuner studio?

Currently it's the free version. I'll pay for the extra stuff if that's what I need to do.

Edited my last post btw. I HIGHLY recommend u get the paid version. This will unlock the autotune feature.

Which one should I buy for what I need?

Get that one. the $60 one. Tunerstudio MS

Thanks,I have it now. I'm on the screen for auto tune. Anything I need to know, or is just click and drive pretty much?

Click and drive. Be very smooth with the throttle and use all of the rpm's

Thanks!

No problem. Let me know how it goes

Without re-calibrating I decided to turn on auto tune and go drive it. I made it to the gas station about a mile away, and when I pulled in the car tried to die. I got it back on and drove home, but it was acting super strange, sputtering and losing power. The auto tune was all over the place changing cells like crazy.
