I have a 1994 F350 4x4, crewcab, 460 E4OD. Last year I installed Banks Powerpack - front to back with new headers and so on. 1 month later I installed a MAF conversion from IST. All in all it was not too bad. I have been getting lean codes and I can make that happen by playing with the throttle. I have done all this in anticipation of my next thing - a new rebuild from Cars by Carl - 385 HP and 510 ft lbs torque. Spec of engine is 9.0:1 compression, Lunati 11601 cam, engine fully balanced and blue printed by Carl. I will run 30 lb injectors, a wideband AFR gauge, heads are F3 castings and ported. I have all this ready to go but I talked to my trany guy about the torque converter - I need to order a new TC that can handle the extra torque did not even think about that. I am also running the Baumann trany controller as well - works pretty good...

I have read the super long thread that 4wheeling79 started - so instead of hi-jacking his thread I thought I would start this one. I am so excited to get this engine in and see how it performs. I live in Utah and mainly use the truck to pull my toy hauler - 8,000 lbs. This engine sucks eggs pulling this trailer. The engine has 245,000 miles so it is time for new power

Take care guys and I will let you know how it goes.

You will need the ability to tell your ECM that you have larger injectors.I suggest the Quarterhorse tuner from moates and the BE and EA software from eecanalyzer.net. Now you can get this motor dialed in properly.Remember its not the Mass air meter that determines your injector size, its the ecm that does that!! hopefully your running a ford lightening or SCT mass air meter and not those POS meters that are "calibrated" to your injector size

The meter I have is a C&L 80mm. Is this going to be a problem?? From IST, I have 'The Air Adjuster'. This is supposed to adjust the MAF sensor input to the PCM. I do know that adjusting this it does make an difference and it allowed me to pass emissions last year. I have heard of the Tweecer and have thought about getting it. I am very much wanting to get this engine running 'top notch'.

Thanks for the info..
Verle.

 

Those lean codes your throwin?? You can thank C&L for that one. The Air adjuster i tried that what a joke that was. Heres the bottom line man, anytime you try and TRICK the ecm into thinking it has bigger injectors = big problems because of injector duty cycles -inj voltage vs battey voltage and so on. Like i stated before the ECM determines the injector size period. I use the tweecer but the QH is twice as good and half the price. Since you already have the WB O2 meter your in good shape buddy. Take my advise and get a SCT BA 2400 meter and sell that C&L meter or better yet just SH--can it along with that air adjuster. Ive owned both and yes i learned the hard way on a N2O mustang OUCH!!. Theres also one other thing you will need the ability to turn off the Adaptive strategy on your ecm "the ecms ability to relearn itself on go back to stock parameters" see why the C&L meter and the air adjuster doesnt work?? good ol adaptive strategy!!

BigLar

 

Thanks Man.... You know, I thought going from 24 lb injectors to 30 lb injectors would fix my lean codes. I have been wanting to install my AFR kit to see what the heck it is doing. But with 'adaptive learn', it all makes sense now. In your opinion, are the 30 lb injectors OK??

 

Heres a great link for you buddy! www.lasotaracing.com/ Don is the man for getting your QH up and running for you so you dont have to be too intimidated by all this EFI stuff ) Good luck man because when you learn to tune your own combo its the coolest thing in the world!!!! and the QH will become the BEST tool in your toolbox

BigLar

 

30`s are PERFECT for your combo NOW but if you add any HP in the future those 30`s are maxed out so you`ll need bigger ones. Also may i add that with the QH you can also tell your ECM what CI your motor is, seeing how VE plays a big part in determining your fuel tables in the ECM. Funny how that C&L meter just keeps losing its credibility ) along with the SNAKE OIL-xxtra super duper air adjuster meter. Im just bustin on you man they got my money too

BigLar

 

And by the way man You have got some nice stuff for your truck and a great selection of parts. take a look at precision industries or lentech or UCC for your TQ. If you pick up that QH make sure to get the BE and EA software from www.eecanalyzer.net. Dont use any other software!!
Carsbycarl motor - Im jealous man )

BigLar,
I looked at their web site - are you talking about buying that computer chip - the QH1?? It looks like it fastens to the PCM board but you have to take the PCM apart. Is that right?? I have seen them just plug into the back of the PCM before. $250, not bad... And the software, well, after looking at their web site I think I have it figured out.
Thanks for the compliment - Carl is awesome to work with. I bought a 383 stroker for my Chevy 9 years ago - it was TBI. Well, what a disaster that was. I hope this one turns out better.
Thanks,
Verle.

 

I was able to just slide the QH into the J3 port with out damaging any parts inside the ecm. Taking the cover off is no big deal though. Its real simple to hookup. The QH is awesome,it allows real time tuning and its a faster processor than tweecer. The reason for using BE and EA are there is a site that has free tuning templates that only work w/ BE. Ill find that URL for you so you can check it out.go to www.eectuning.org for so great info on tuning and the QH

BigLar

 

Here`s the site for the tuning templates Welcome - [tunexchange: It's a bird... it's a plane... it's TUNEXCHANGE!!!] watch his screencast on how to do it. This is a very cool site for newbie tuners. Wes is a really good guy with alot of knowledge.
With all this info you should not have any trouble setting up your QH.
Good luck you have alot of expensive parts there and you definetly want to get it right the first time. Question? is your cam broke in yet? If not check out the Camking 2000. Its a service offered by MPG heads. Im definetly going to send my cam to them!! Its something i really worry about is flattening the cam lobes on startup. From what i understand just having the starter turning the motor and it doesnt start or for some odd million reasons, the cam can become garbage real quick. I do have Joe Gibbs breakin oil though and will use moly on the lobes and the lifter bottoms. Ive also read a million posts on this but with EFI you just never know if its gonna start immediately. Heres the site for the Camking 2000 Welcome to Cam Research Corp

Keep me posted on how things go for you

Larry

 

Thanks Larry, tons of help and I can't wait for warmer weather. The cam is not broke-in yet, the engine is assembled (straight from Carl).

I'll keep you posted on the progress - thanks again...

 

Im waiting for the warmer weather myself. Worst winter in NJ ive ever seen. good luck and keep in touch

 

Larry,
With all the stuff I have read and the learning curve for the tuning, I think I will get a dyno-tune done instead of 'guessing'. I just don't have time to play with it. I travel for work a lot and when I am home - I am home. I get into trouble if I don't spend time with wife and kids. I did not even know there was a speed shop in town that does this kind of stuff. I did some searching, I called them up tonight and the price is not too bad (I guess). All in all however, when it is done - it should be perfect (I hope). Plus I will have HP and trq numbers to post. Can't wait!!!!

 

The learning curve is steep but very satisfying. You can always do it in the future. The ford ECM is a fasinating piece of technology. Thats why i directed you to Don Lasota for the initial tune. If you go to a dyno make sure you get a SCT chip and possibly with multiple tunes you can switch back and forth depending on what your using your truck for.It took me a long time to learn the tweecer believe me so i understand. Good luck to you man and hope all goes well for you. like i said you really did chose some fine part combos for your build. I should be putting together my combo soon. I went w/ a motor"speedpro hypers-ARP main and rod bolts and the block decked to bring the quench into the .045 range" from Steve Brenner "hemifordman" and im replacing the entire exhaust system "Hedman coated headers w/ a magnaflow Cat" and the entire fuel system '"All new parts" and the emission system. Also im rebuilding my C-6 and putting a lower stall convertor from Hughes. My Goal is to get better MPG- durability-and reliability. The cam is from Comp X256H-14 so it will give the ol 1988 F350 dually a little Umpfff. Keep in touch

Larry
