Thread for those of us who tune our own cars
I just picked up the SCT Pro Racer software from VMP. I'm hoping their are some other people on here that do their own tuning and we can use this thread to help one another and recruit more people to start doing their own tuning.
I'm starting out tuning my crown victoria DD, and once I feel comfortable enough with the tuning process I'll move onto tuning my Mach 1. The only two options I found to purchase the SCT software was through VMP or Lasota Racing. There are mixed reviews on the SCT guide and Lasota's tuning guide. I'm familiar with the various parameters within the software and I'm unsure if I should even buy a tuning guide.

Re: Thread for those of us who tune our own cars
I liked Lasota s tuning guide my eaton mach was my firat time tuning it was a good resource. Ive tune a few cars since. Still refer to it once in a while. He was also alot of help early on. I called him once on a vortec fox i was tuning whe i had no maf transfer to go off of was very helpful.

I guess I'll order the lasota guide. I heard mixed reviews on it. The SCT one is too pricey.

Re: Thread for those of us who tune our own cars
I own the PRP software as well as the Lasota book.. Ive read the book and it really does help, he goes over some key features and tips..I cant wait to start using mine when my pile runs..

Re: Thread for those of us who tune our own cars
ive got the lasotta book, Ive made it through writing a base tune from scratch and its extremely helpful imho.

Re: Thread for those of us who tune our own cars
What are you guys using for datalogging air/fuel? I had the LC1 but my buddy picked up the LC2 and its significantly better than the old LC1. So I bought the LC2. Are you just using the SCT analog input USB cable?
Or is there a way to interface the Innovate software with LiveLink? Lol at the changing plugs comment.

I have a PLX wideband hooked to a serial cable. I plug that cable into the Xcal2 and choose analogue one on fhe Livelink.

Re: Thread for those of us who tune our own cars
Great. I got the LC2 installed and purchased a firewire from Best Buy. I got the Insignia 800 with adapter for 6 and 9 pin IEEE1394. Wire colors are the same as this guide for how to wire it up. Time to datalog!
http://www.focusfanatics.com/forum/s...d.php?t=177202 Edit: In case the link goes away, white is not used. Red and Orange are for the 0-5v output from the wideband. Blue, green, and black are grounds and are not used. It is a one wire connection only, you don't need any other wires for the firewire.

Re: Thread for those of us who tune our own cars
I've tuned my turbocharged Mach1 with all kinds of mods done to it. I put a powerglide and stall in it rewired the speedo to work put 160lb injectors larger maf and housing TB ported intake, had big cams at one point. etc. I know a little bit about a little big when it comes to tuning these cars.

Re: Thread for those of us who tune our own cars
Is this just datalogging thru the handheld or with the Livelink software as well?? Why am I here?? I just read question I asked and doesn't even make sense to me Am I the only one with a Autometer SportComp Wideband? Wiring I guess would be different? Great thread, confusing for us analog types personalities still with flip phones, but interesting

A personal preference is I don't mess with intake manifold volume or displacement to change load scaling. I was taught to fill these out correctly and load will be whatever it will be. The spark tables can be scaled to match whatever load is. With my first combo my load was maxed around 1.3-1.4. So I set my max load to 1.4. This also gives more resolution down low to dial in timing. I spent a lot of time tweaking the low end of my timing table. That's why my last set up had decent throttle response. Quote:

Re: Thread for those of us who tune our own cars
Anyone have tips they had to learn the hard way, or wasn't available in the tuning guides?

One of the main reasons I wanted to do some tuning was to dial in the driveability. Since most tuners don't take the time needed to perfect the tuning under low load. On the mach I have the hpx maf, blow through. And the crown Vic is an 05 so it is a new slot style maf as well. Running 91 and turning up the timing under light load should help my gas mileage and throttle response. Thanks for the good info!
I think I found out the reason my mach has been having issues in the winter.. is its not getting warm enough to go into closed loop so its idling weird and having some driveability issues. (160 inline tstat with a hole drilled) Plan to spend a lot of time in the low end of the timing table. Do you guys keep the generic maf transfer functions recommended or do you change it? I heard some people will go as far as putting their maf setup on a flowbench?

Re: Thread for those of us who tune our own cars
btw it is going to be in closed loop untill you hit 555 or higher in the load range unless you changed that section like I did to zero to keep mine in open loop all the time and not use the o2's at all. It will be in Closed Loop no matter what the temp is. I also run a 160 degree stat with 4 holes drilled in it and a 3 core LFP radiator. also 160lb injectors No issues at idle

Good to know. This lasota tuning guide is great. I don't get why people were bad mouthing it. Lots of good info.

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...

I was able to change the temp mine was considered warmed up. I think I changed it to 140 degrees. Since I only drove it on nice days I wasn't worried about it too much.

Re: Thread for those of us who tune our own cars
What are the most fundamental parameters you change over the base value files? With the 100s of options its hard to narrow down what is critical and what parameters most tuners never touch.
Also, what are the key parameters to change when tuning an auto? I'm upped the global pressure because i didnt get how to do it incrementally by gear. I'd like to increase how long it takes to upshift while cruising so i can rev the gears out longer, but the lasota guide is vague with their auto tuning info. Ahhh. Found it in the shift/lock schedule. Perfect. I also set the 1-2 and 2-3 torque reduction on upshifts to 1. In first it had values of 2 in lower rpms from the value file. I must have changed something because it doesn't seem as loose when you floor it in first anymore, it used to feel like it flashed to 2,500 off the line and then engaged. Now it lugs off the line more. Not sure if it was because it was slipping in 1st or...thats how it should feel. Reduced lock delay. Trans is shifting great, think I have that dialed in good enough for now. Note on the firewire cable...you don't need to run a ground to the firewire ground. Just plug in the analog 1 or analog 2 wire to the output on the wideband. Wish I had known that before, oh well.

Re: Thread for those of us who tune our own cars
Didn't know about the open loop delays for WOT. I also didn't know about the aircharge WOT multipler. Went WOT and ran her near lamba.
On a good note, I think I got the MAF transfer function dialed in pretty well. Pretty much within 2-3%. I really like downloading datalog data to excel to analyze it. Do you all tune to 14.64 as stoich or did you adjust to ~14.1 to account for the 10% ethanol? And then just base everything off lamba from there?

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.
