Ecu tuning

A bit off topic but....the BC adaptor is holding you back.........It can't breath.......GT40 lower is SO MUCH better.....

Yeah they cost a fortune and will still need tuning

We can’t get ahold of EFI guy, he doesn’t answer or return calls or pms.

He moved out of the City, Bought property, and has moved in. As with any adventure when you buy property, there is a lot of deferred maintenance that needs done... Not only in the living space/land/shop/barn/out buildings/well, etc. I am pretty sure he has a shop set up, and is working on his back log of work to do. (4 months, since we spoke last) Being a one man shop, answering everyone's inquiries when they call/email/text/FB message would be impossible.

So he is not ignoring you, he just takes a while to respond...

Doug.

Good to know. So keep calling is what you’re saying?

 

[904Bronco]

If you have left a message, give him a few days to respond before you try again. I have sent him a text and waited a week for a reply.

He is the kind of Guy who wants to be helpful and help folks get their projects on the road. To the point where is own Bronco isn't a daily driver and he has had it for a few years... All of us have to balance that quality of Life thing along with Family and Work.

 

[Timmy390]

If you want performance it's not cheap. Deals can be found....I got mine for $350 shipped. It's the cast iron version but works the same as the lighting version.

I guess I'm trying to say a tune will only get you so far. You have a bottleneck at the adaptor that no tune can overcome. I considered going with the truck lower and BC adapor but in the end I bit the bullet and went GT40 lower......

I saw a lightning intake at Carlyle one time and recognized it right away and the guy wanted 900$ for it.

 

[duffymahoney]

Lightning intakes have always been high, well at least the last 10 years.

 

[stupidboy]

Does edelbrock or Holley have substitutes?

I used Decipha to tune my 408. He's still working on it, I'm not completely happy. And he's not that easy to reach either. To be fair my 408 is pretty far out there tuning-wise, compared to the nearly stock 5.0 that I had before, and he's pretty close.

Agree with the other comments about the truck lower. And a stock 351W, assuming it's a truck engine, doesn't make a lot of power anyway. If you are stepping up from a bone stock Bronco 302 then yeah, it's a big improvement. But with stock iron heads, intake and cam it's probably never going to make much more than 250 HP, if that. And the stock A9P tune probably isn't that far off. If you want a big bump in power go looking for some aluminum heads with small/medium runners, the Lightning intake, 24 pound injectors and a probably a different cam. That will really wake it up and you will definitely need a different tune. A friend of mine did just that to a worn 351W van motor. All used parts except the cam. The difference was amazing.

 

[stupidboy]

It is a truck motor, but like I said the explorer 5.0 in my sons Toyota has more getup. The truck motor is not wore out either.

 

[stupidboy]

I’m not looking for big power, just better running and I agree with the breathing issue but I think a tune on the computer could compensate for that and the 49 more cubic inches.
It might be that my transmission not downshifting at stop signs is the problem, but occasionally upon start up it will pop through the tb when given it’s first burst of throttle.

Edelbrock and Trickflow have aftermarket options, Lars and I run the trick flow stuff, it is slightly taller than the edelbrock but it is more expensive. I wasn't super happy with the fitment of the trick flow components. I would definitely fork out the extra for the edelbrock if I did it over again.

I don't think you are going to get what you want out of it from tuning in my opinion. I agree with Lars, and I almost mentioned it earlier, a stock 5.0 computer would probably run that all stock 351 pretty well. Explorer set ups just run so much better in general it's hard to compare yours to your sons. I have basically what Lars suggested, a 351 stock bottom end, with a cam, heads, intakes, injectors, throttle body, MAF, running off an explorer computer with EDIS tuned with an SCT handheld through decipha. I am only in my second stage of tuning but I wouldn't say mine feels like a power house. Honestly the stock explorer 5.0 before I yanked everything out seemed like it revved nicer and quicker. Full vehicle set up has a lot to do with it as well, gearing, tire size, and transmission will play a huge part in the end result. It takes a lot of power to push through an auto trans, t case, and big tires on a Bronco. I know mine won't even come close to lighting up the 37's on pavement. Would probably do it no problem with a manual and a clutch.

 

[omureebe]

Are you running a mild 351W and C4?

 

[stupidboy]

Hmmmm maybe have to rethink everything before I start spending money on it again.

 

[stupidboy]

Are you running a mild 351W and C4?

Stock 351 truck motor and c4 with 350 gears and 35s. Even at idle I can tell there is a difference between this and explorer 5.0

I have a mild 351W and c4, 350 gears and 33"s. I have two EFIGUY flashed ECUs - do you want to borrow one and see if it does anything?

3.50 gears and 35.....Oh that's a much bigger issue than the BC adaptor. And that C4 isn't long for this world with those gears. It's generating SO MUCH HEAT

Screw the tune....Buy a set f 9 inch gears 4.11 at a minimum and see how much HP you just added. With the C4 I would run 4.56's but that's me.

For scale. I run 4.11's with 33's and 5 Speed.......It rips......If I had it to do over again.....I would go 4.30's just for more ripping....

[DirtDonk]

So, 35's and 3.50's and a C4? What tire and gearing behind your son's 5.0?

My Bronco is stupid heavy at over 5000 pounds with full hard top, bumpers that are apparently lead-lined, 35" tire on 17" wheel combos that weight 90 pounds apiece (5 of them) etc. My 408 made almost 470 HP on the dyno. Probably less than that in the current installation, but the 500 ft-lb torque at 3700 rpm number is still probably pretty close. It feels moderately fast, way better than my 250-ish HP 5.0, but it's still no stoplight rocket even with a manual transmission. That said, I'm running 4.56 gears on 35" tires with an NV4500. No way would I want anything taller. Off the line it doesn't feel much different than my trusty (and great running) 5.0. It starts to matter once the revs pass 2000.

You need lower gears. Sounds like a PITA but you will like the results. At least 4.11 and if you think you will ever go with an overdrive transmission then at least 4.56.
