Re: 3.7l performance love

idk if this will help anyone, but if any one with th 3.7/4.7 want larger fuel injectors that are easy to find, you can pull them from any ford 4.6 (GT-2v V8 thru Cobra/Mach 1 3 and 4v V8 and f150). they will work because they are the same style as the ford ones and both are made by bosch. i am begining to wonder if other ford electronics would work. the injectors do and not cel

Re: 3.7l performance love

Sorry, but I have to speak up here. I strongly recommend AGAINST swapping injectors without retuning. The stock PCM and subsequent fuel injector related tables are designed around the stock injectors. Can you make bigger injectors work? without retuning? Maybe. Would I recommend it,,, NO. And additionally, without datalogging to watch, you have no idea whats going on. Subpar calibrations designed around a stock engine , plus a subpar strategy to dump enough fuel, plus little or no verification via hard data, yields subpar results.

Do it right, or don't do it at all. I'd be willing to write VE/spark maps (for a fee) for you guys to send to Dave @ B&G to transfer into one of his PCM flashes, if he'd be willing to add it to what he does.

Re: 3.7l performance love

IMHO you should stick your stock injectors back in and get ahold of someone local with a wideband o2 and possibly a dyno to see where you are as far as a/f and injector duty cycle. With the mods that you have I think the stockers are fine because all you've done is made the motor more efficent. You really havent added any power i.e Nitrous, turbo, s/c.

Here's what I use to help tune my turbo cars.

well i understand what your saying. but... i did install larger injectors as a safeguard against running lean and thats because of how efficent its been made to getting air in and out. and i did retune it. granite a canned tune from hypertec. i do have evidence that they help, but its not strong evidence. after they install (before the hypertec tune) i did pick up about a tenth at the track and the truck did feel stronger from the mid range up.

about you doing VE/Spark tables, i thought and i quote that you dont do 07+ up because there is no support from sct. are you able to write a tune without the stock calibration for 2008? How much if you can, tax time is almost here after all. if i go with a B&G tune i want 91/93 octane tune, and a modified torque management and the "no governer" that i currently have.

Look, im not arguing with you since you do have more experience in tuning the pcms on the wk then me, and im not gonna lie i dont know much about it. but i am good at mechanical tuning tho. i do agree me installing larger injectors may not have been the best decision, but ive been running them over a year with no ill effects.

maybe, but im not pay 500$ to dyno and no one around here will do stock pcms...i tried. I know about innovate, good stuff and i installed an LC-1 wideband on a project car a while back, that and we ran ECMlink (DSMLink as previosly known), that project got scrapped when the engine expirienced crankwalk

Sorry, been a little busy...

That logic is all well and good, but what about your fuel trims? How do you know they aren't pulling fuel at WOT?

I'd expect anything beyond the stock tune to help, the stock timing on a 3.7 WK ('05 is the only year I can tune) is extremely mild.

a PCM flash is 350.00. Tuning these will be an expensive venture regardless how it's done.

Re: 3.7l performance love

Actually i dont know for sure if they are pulling fuel at wot. all they said was that they optimize fuel and spark at all throttle % from partial to wot. i also know that these things run a little rich out of the factory just by looking at the amount of carbon in the exhuast. inside of my tip is black from it. i believe that a slightly leaner mix will get better power from it. i ask hypertech if they can remove torque management. they said they could, but their higher ups wont let them for insurance reasons. if they staat doing that then they run the risk of trans damage and hypertec dosent want to be responsible for it. anyway the tune will have to wait, money gonna be very tight for a while.

So I read this entire thread today from start to finish, great information. I have some questions though, I am very unfamiliar to tunes and most stuff dealing with the engine and exhaust. Can anyone give me a comprehensive and cost efficient way to get some power from the v6?

After reading it seems like the best mods to do would be throttle body, cold air intake, one of the tuners, and then add a new muffler or even exhaust system.

well i think the MOST cost efficeint way to gain power out of the 3.7 is a tb, cat-back exhuast and a tuner, should net you bout 20-25 horsepower, the 3.7 and 4.7 engines love airflow so the better you can make it breath, the better

Cool thanks what order would you do those in? Or does it matter?

Also your referring to the hypertech power tune right? Does using that tune put any extra wear on the engine and stuff or is it all safe to do? And this may sound dumb but tb is throttle body right? Thanks for the input greatly appreciated
