Spot check my tune?

stampy167 · Aug 23, 2021

Hi All, I am hoping someone might be willing to glance over my current tune for my 95 Mustang with Trick Flow top end kit and some other mods. Happy to expand on that if needed. I assume that is the most important for the tune but .I
The timing is set up properly but I am not super confident in my timing table. Everything past 1300rpm on the fuel table has been done through VE analyze and AFR table.
The idle is still a little hunty and goes from like 850-1200 at times.

I have attached my current tune and a data log from startup ( I believe I started datalog prior to starting) and driving around at varying RPM's for 15 minutes or so.

Any help is appreciated. Thank you

Perhaps someone can point me to a tuner who works with Megasquirt in Illinois or Michigan? I tried paying a remote tuner on MSextra forums and got nothing other than an inability to pull the car out of the driveway and pegging my AFR as lean as it will read for $300. I am back to the tune posted in my first message since it drives with it.

im sure a91what will help you out! he tuned my car and it runs great!

I can do a remote tune for you, I will even do the first session with a no charge clause just in case I cannot help you.

The tune is ....... messy give me a few to look it over and make some changes

Thank you, I would very much appreciate that. I can tell you / send you what was taking place with the guy from MSextra too if it is helpful.

he didnt really do anything besides charge you money... so I am going to gut it anyway

Lets start with this, please datalog it for me. I made lots of changes so some roughness is to be expected.
Can you give me a parts list and a brand for the wideband so I know what you are working with.

Science and math and stuff....

Might be why your tunes are turning out better than the my method

stampy167 · Aug 30, 2021

Thank you,
Wideband: Innovate 3918 MTX-L
Trickflow twisted wedge heads, track heat intake, Track Max cam

70mm throttle body
AC Delete
Smog Delete
EGR Delete
Anderson 4" Powerpipe.
Under drive crank and waterpump pulley
BBK shorty headers, catless x pipe, flowmaster mufflers
4.10 gear
MSD 6A ignition box (w wire harness so easily bypassed)
Bosch 42lb injectors
255lb fuel pump (have a supercharger waiting to go on)
adjustable fpr

I think that is it for relevant parts.

Well, I am both pleased and upset. Pleased with the tune and upset I paid the dude from MSextra. Idle seemed steady. I sat there for a bit and let it get up to around 140 on coolant temp before taking it for a ride.

a91what · Aug 30, 2021

Ok, Lots still needs to be done. AE settings need gone thru and the injector settings are totally wrong for [I assume green top 42lb].. this needs to be addressed but will again need major tune changes. The idle could be much better but thats just a few keystrokes.

I can make these changes for you but it may be a rough transition.

I took the liberty and made the needed changes to correct the deficiencies.... let me know how it does it may not even be driveable.

stampy167 · Aug 31, 2021

You were correct on not being drivable. Lotta smoke. Unfortunately it wouldn't run long enough for the wideband to register (at least not on the gauge). Hopefully this log is large enough to get some useful info from?

a91what · Aug 31, 2021

Did you power cycle after loading the tune? Always power cycle.
I assume crazy rich?

stampy167 · Aug 31, 2021

Powercycle by unhooking the negative battery and turning headlights on? I did not know I should be doing that but can go do that now. Yeah smelled like I might sting some eyes.

stampy167 · Aug 31, 2021

Just checked the ole Googles, just load the tune to controller and then turn key off to power off MS and back on is all that is needed?

stampy167 · Aug 31, 2021

Ok, it drove that time around but it is pretty rich and bucked pretty good under 2k. Short drive, I didnt know if you would need longer for that.

a91what · Aug 31, 2021

You got it right

a91what · Aug 31, 2021

The only change made here is to the req fuel value, I do not want to remove 30% from the fuel table as that will make the numbers at idle much smaller than I like them to be.. Please try this and we will make a change from here.

You will likely need to check or change the plugs after we get done with the next few steps
