but I should have had proper tuning dammit, I drove 4 hours each way for it. Guess it's time to contact Speed Inc.

Adjusting VE tables for superb cold starts takes lots of time. Most tuners would have to raise their prices to take the time necessary to get them all spot on. It's basically like doing a speed density tune, then rescaling your MAF to make everything agree with your VE table s-trims. It's no simple task as every car is different.

Pat G, is right on the money again. The last time Mikey tuned my car he spent close to 2.5 hrs and 10 dyno runs. The tune is awesome might I say.

Not to hyjack, but I have the same cold start issue with my car. I took it to speed inc last fall and was basically told they couldn't fix it, wtf? I will be making a trip back there soon, luckily I'm only ~ 1.5 hour drive away. I am kicking myself for not spending that $450 on my own hptuners copy and a couple hours of dyno time...

well now, that is now what I wanted to hear...

they did 3 passes with my car, pretty much nailed it from the get go with the first pass putting down 427 rwhp, and the 3 (and last) only getting 429 rwhp...the entire process took about 20 - 30 minutes....so you tell me, did they really invest the proper time in my car or not?

I was hoping that Larry from Speed Inc would pipe up by now, but I guess I'll have to send him the link and ask him to clear this all up.

There is more to a tune then just strapping it down to a dyno and getting the WOT dialed in. IMO, a good tune will take a few hours of street driving and logging along with dyno time after the street tune is dialed in.

that is definately how I feel as well

Holy cow Fultilt, not sure how I messed that post! congrats man, it'll be a beast!!

I emailed Larry at speed Inc, he emailed back right away and sounds willing to take another look at it. Unfortunately, it would require me driving another 4 hours each way, and leaving it on their dyno overnight so they can actually simulate a cold start up.

I'm telling you, it's not necessary to look at the car dead cold if you have the VE tables nailed. Speed Inc will have to log lots of miles on the car to get the cells in the VE tables zeroed out. They'll also need to re-scale the MAF once the s-trims are close to zero since the two rarely match.

Trust me on this, I fought cold start issues for a while after my cam change. Tried all kinds of stuff. Once I got the VE tables correct and the idle airflow factors correct, my cold start issues went away 100%...even with the a/c engaged. Speed Inc won't need to have your car dead cold to fix this problem. As a matter of fact, it needs to be fully warmed up to fix it.

I agree 100%. The car needs to be dialed in for the VE table and not have the IFR table adjusted with the maf still at a stock setting. IMO the correct way wouldn't take all that much time, but would require street driving the car to get a proper load on the automobile.

well, maybe I'll get my own programmer and start learning this stuff, I don't know...thanks though.

LS1 Speed made it sound as if I'd have to leave it their overnight so they could start it up completely cold.

I contacted Larry and got the same response...

ok, while I'm pumped for my friend, I'm now really ticked about my tune.

We just finished installing an F13 +4, PRC 5.3's, rocker arms, underdrive pulley, fast 90/90 set up etc....he sent his pcm to Alan at Futral for a mail order tune to get the car drivable for the long haul on the power tour this week...

Man, we fired that fugger up and it ran perfect. Absolutely no searching for idle at start up, idles right at 800 without quivering, no hesitation, no nothing...

so is Alan the man, or did Speed Inc miss this one? When he tells me how he talked to Alan of a few occasions before his PCM was tuned, and how they discussed in length what he was looking for on his dyno results, I think Speed Inc missed mine badly. There was never a discussion about drivability versus peak HP, driving habits etc etc....they simply took my money, and 45 minutes later sent me on my way...and of course, that being my first tune I think I learned the hard way.

Lessons Learned I guess, I kind of just trusted them after all the positive things I read about their tuning program on the site.

Well I'd say Allan definatly knows how to tune his cams. Mail order will get you going, but a true tune setup on a wideband is what you need.

I'd think it would take a little longer than 45 minutes for some tuning however.

hey 1badmofo i know this is off topic but if u have a chance id love to hear the setup ima have a very similar set up in a few weeks

oh man, it roars...I tried to get a sound clip with my digital camera, but that thing doesn't record anything other than normal sounds, so it was all distorted. I'll keep trying though.

Just my opinion, but it would be worth your while to invest in some tuning software, learn about your car, and fix it yourself. There are very few people that will take the time it requires to get your tune dead nuts on (and that means every aspect, from cold starts with the A/C on to just putting around town). It just isn't cost-effective for the company. Unfortunately, that's the name of this game.
