Brice's NA V6 Build

What are your ecus trims?

 

Pretty much zero at idle
But they are 5/+8 max
They are usually 3/+3

 

Not sure man might be something with your MAF. I don't use any skew on mine. It's post IC. How high do your MAF voltages go? Have you tried taking the clamp off?

 

Precisely. If you are in a 100% OEM truck cruising at stoich, then increase load to borderline open loop conditions it will still be stoich, then go that little bit higher in load where the truck switches to open loop and bam, stoich goes to rich, rpm, tps, maf all around the same values.

Read URD's piggy back tuning guide, does a good job explaining this and how to data log so you can try and find this switch point through the map and tune for it.

 

Yup... my truck does that. When I’m going 75mph+ and I’m close to 0 on the boost gauge (not in boost), it will hop into open loop and my AFR’s will go rich

 

I think the year models differ but my year (99) doesn't engage open loop until 80% or more throttle input from what I have found, other than 80% throttle no other condition triggers open loop. I'm still trying to figure out open loop, but I think i need to subtract a bunch of open loop fuel cells.

 

The build lives!

I am getting close to fabrication time for my turbo exhaust. We'll have to have another get together then.

 

I'll be updating this build real soon with a buttload of pictures once I get some suspension parts
And another get together would be great! Last time I was there I didn't even get to check out your truck! Just lemme know when.
Also, I guess you got a welder?

What do you guys think of these?
I was looking at a forum member's wheels that would need new tires and a repair on one of the rims. Price of rims- $300 Price to fix bent rim $115~ Price for tires $450~ +balancing and rotating is around $900 give or take a little.
Or
The above takeoffs for $800 (maybe less if they'll make a deal) for balanced rims and tires all good to go.

What do yall think? either set will let me upgrade the less than stellar stock brakes.

 

Leaning towards the takeoffs
gonna contact the guy.

 

Welp scheduled to go pick up the rims and tires friday, wish me luck

 

Cool man!

 

Alright so apparently the 1st gen offset is different than the 3rd gen offset which means I'll need spacers to correct it (No I don't wanna argue about spacers lol)
I believe 1st gen offset on the 15x7 Prerunner wheels is +3.25 and the 3rd gen offset is +4.5. This means I need a .75" spacer to correct it?
Do you guys know of any good spacer brands? (@Torspd) It's sorta hard to mess up a hunk of billet aluminum so I figured as long as I get one with quality studs I should be ok.
Also do y'all have any recommendations for spacer thickness? Most places only sell 1"-3" Although I don't wanna go over 1.5"

 

Just make sure they are hub centric spacers

 

I ended up buying the rims and tires! 180 miles on the tires and wheels and they are in great shape. Truck also rides much better with newer better balanced tires
I think I may have to swap my lugs to the washer style vs the centering style

 

Figured I give a small update. I did some more closed loop tuning and I think I'm pretty solid. Idle trims at operating temps are literally 0. I still need to work on my Vacuum to atmosphere to boost transition as it tends to get rich. And there's a few spots in closed loop where the trims are -(+)10 and could be improved.

I also got some of redline tuning's hood struts in the mail the other day so I should be installing those this weekend

@Torspd we meetin up this weekend?

 

Yes sir. I plan to get off of work around 1 P.M. on Saturday. Then can meet up shortly there after.

 

That should work for me

 

Looks wicked man!

 

Ended up using OEM lower ball joints from toyota and used some Acdelco uppers that use the same OEM design with the nylon bearing seat and polished ball joint and they were only $30 a piece. At this moment I believe the AC delco uppers are a valid equal to the OEM uppers, but I haven't found any replacement for the lowers, and I don't think I will. I don't guarantee they will be the same thing if you order them, since aftermarket manufacturers tend to change designs for some reason. They even use the "555" stamp, which basically means nothing from an aftermarket source, but considering the OEM design I believe they are genuine "555" internals. I also went to poly control arm bushings.

Pics to come when I finish

AC delco uppers (they come as pictured, and have a very nice machined finish)

Tie rods

Sway bar end link

After installing all Of this I will be nearly all polyurethane bushings! (excepts for the rear leaf springs and the coil bucket bushings)
-Steering rack bushings
-CA bushings
-Sway bar bushings
-Tie rod boots
