I did an intake swap for a local guy (TBSS intake on a 1999) he had the retuned pcm shipped to me before he brought the truck over for the swap, after swapping everything over the engine would only run about a second that stall. (even with stepping on gas) at first I thought it was a security or crank relearn problem, but ruled those out. After going through everything and checking all the connectors I noticed that the MAF was not plugged it, plugged it in and the truck fired up and ran just fine.

 

I've unhooked my MAF before, it runs just a hair rich, but still runs just fine. Maybe it's a problem of custom tune vs. stock tune?

Anyway... I'm glad this got figured out and wasn't anything major. I think we're all about as excited as you are to see this project finished.

 

i beg to differ. you have no idea how bad i missed my truck. i have been reduced to driving a ford. friends dont let friends drive fords.

the reason its not running without both connected is because the computer has had no learning time. once the computer figures out the tune/engine i could run without the map or the maf.

 

Yea that just means the fueling tables are so far off in the tune, it won't run. Hopefully the VE is close enough that when you get the MAP in, it will hold an idle. Can't wait to see a vid of this thing running.

 

is that normal for a safe tune or do you think Wheatley made a mistake?

 

He probably made it pretty rich and is wanting the fuel trims to compensate. The problem is that the engine has to run in order for the fuel trims to update. Just get the map on it ASAP and see if it idles.

 

ill have it on tomorrow but my issue has been i cant find any info on whether or not the wiring on my trucks harness the same as the 07" map sensor. it it is ill have it on in a matter of minutes

 

oops 07+

 

Im using a 2007+ map sensor on my 2005

 

Charlie is a good tuner but getting everything right in a mail-order tune without logging anything is a pretty big crap shoot. I'd be surprised if 20 percent of all mail order tunes ran decently with that many mods. You need to get it to a tuner who can work with the car in person.
