Re: Thread for those of us who tune our own cars

I would tune for what you're going to find at most gas stations in the area personally, if that's the 10% ethanol I'd tune for That

Re: Thread for those of us who tune our own cars

Cool. Thank you.

Now I just need to learn how to manipulate the spark sources to obtain the timing I want, and I'll be ready to start tackling the mach. At least I'll be able to do some decent datalogs of the current tune on it, even though its not perfect, and I'll try to replicate it. Then I'll try tuning it with the 60lb injectors I've got, and then I'll try e85.

Re: Thread for those of us who tune our own cars

I wonder if you can load tunes in the spftware made by other tuners (like Bama, etc)? It would be interesting to see what they changed just for education purposes at the least.

Re: Thread for those of us who tune our own cars

The file they send you via email is in a different format than the one saved from the software. They would have to send you the tune in the file format they use to edit it in the software, which they likely wouldn't do.

.mtf is the format to edit the tune in Advantage
.cef is the format used to upload using SCT update manager

Agreed,.. I never understood that myself.. And if you purchase the PRP software from Lasota like i did .. He will write you a base file to get started from your mods list... The cool part about this is, You can either use or go off of it to make your own..

He wrote me an E85 base file , but ive been working on a 91 octane base file myself.. Its fun but tons of reading.


On a side note, What tuners(Which sct handheld) are you guys using ??.. I had a XCAL2 that i cannot get this laptop to reconize.. thinking about getting a new laptop or new SCT...

Re: Thread for those of us who tune our own cars

I had a ton of issues with getting my laptop to recognize my handheld (x3). Are you running windows 7 or 8? If so, you need disable user accounts and manually install the drivers. Then it will work. Took me forever to figure it out.

Here is the link for the how to:

Make sure to store it in the C drive under program files, sct. Or it won't work either.

Re: Thread for those of us who tune our own cars

I still can't get the car to hit my commanded lamba at WOT. I've got the MAF dialed in, and the base fuel table set to ~.89 for TP 500+ and it will still follow the MAF curve at 1.0. TP is throttle position right, to TP 500 should be half throttle? I wish my base fuel table was off load vs TP.

Take a screen shot of your base fuel table and post it.

It took me forever with my new laptop with Win 8, then with 8.1. I gave up for a few months, then I tried with their newest device flash and drivers. That was last fall I believe.

Agree, I have Windows 8 and never could do it , finally got TeamViewer and SCT remotely ran my computer and did it for me..then coupla months back I did a reset and lost drivers and stuff , so I am calling in the morning to do it again. All I remember was they did it as administator and I think had to turn off my Kaspersky security, guy said Windows 8 was hard, that is why my computer freakin keep trying to update to 8.1 and I keep telling it to pack sand...good luck guys.

Here is my most recent one. Its how it was setup in the value file, all I did was add some more fuel.



I'm going to try it like this and see what happens. I just don't want it going open loop when I'm at half throttle and killing my gas mileage. I guess I can datalog fuel source to see where its pulling from.

Re: Thread for those of us who tune our own cars

if you really want to read a locked sct file the Sniper tuning software claims it will do it but its another 300 bucks (or if you know someone that has it...)

Re: Thread for those of us who tune our own cars

Thanks. PM sent with my number.

Yes, this is for my NA Crown Victoria. I am using it as practice since its going to be nearly impossible for me to blow it up. Once I am comfortable I'll start tuning the mach, which would be easy to blow up given how hard I drive it and the boost.

Don't get greedy and you'll be ok. I had a whopping 10 degrees of timing in mine for a long time. And make sure the spark table is scaled correctly. Didn't do that once and saw 22 degrees at WOT. Oops.

Once you go WOT your car will swap to open loop and use the maf transfer function and not use the o2's which are used in your base fuel table. IE your base fuel table is used at part throttle not WOT. And if you are having issues getting your commanded lamba at part throttle data log your short term fuel trim to make sure your o2's are working correctly and one of them aren't being lazy.

It is some good software and if you plan on changing or adding power mods it is very good to have and learn. I'm always making changes to my car. Mainly timing curves and a/f at different boost levels.

A time consuming process no doubt but it's nice to have the control to make changes when need. Especially when changing set ups.

What are you talking about? the base fuel table is not used at WOT? WTF
then what does it use?
if you are commanding .89 as i see you are in your table then your maf transfer function is wrong.
can you post a log of your WOT run where it is hitting stoic at WOT?

Re: Thread for those of us who tune our own cars

MAF transfer function ended up being wrong. I had the wrong injector data, apparently some p71 vics have 24lb injectors and some have 19lb. Once I put the right injector data in and redialed in the MAF, it is all good now. Still needs a little tweaking though as its slightly off. I used a smoother transition in the base fuel table so it gradually transitions from lamba.

As far as the MBT table is concerned, I'm trying to adjust my BKT table so I datalog as close to the MBT spark values as possible. Is this the right way to approach it? So far it is really helping to improve the driveabilty as my low and mid power has improved noticeably. Assuming Ford has the best data in the MBT table, for an NA and centri car wouldn't you want to use this data to model your timing and then scale down once you reach higher boost levels? Anyone have insight on how increased cam duration affects your MBT? Just curious how I will want to model my timing on the Mach with the cobra cams, I guess I can get SCT to provide the value file from maybe a 01 cobra, since they have the same heads we do and compare it to the Machs MBT table.

Re: Thread for those of us who tune our own cars

As for timing youd be better off using a timing table from a cobra as it uses the same heads and factory boost use your stock timing table when bot in boost and then pull it back once in boost. Im running 15* timming from 2k-7k and at all boost levels car runs great.
