Drag and Drive Baja

Update :

Picked up a rebuilt TD04-13t last night. Working on an adapter and a hook up for my 02 sensor.

Realized how far off I was in what a reasonable turbo size is.... I’m embarrassed to say the least.

can anyone clarify lambada delay and tuning? Feel like this is about to be important. Also does anyone have there ECU set up for boost safety.

Thanks
Ben

Another one with a td04 13t.

Welcome to the club. I love it!

Lambda Delay is for telling Autotune how many milliseconds it takes for the exhaust to get from the head to the O2 sensor.
You can study log files to kind of figure it out.
The default settings are for a V-8 engine and not really close to a turboed VW.

I have my boost cut for what I feel is max boost. Right now I have it set at 275 kpa.
You can set it to whatever you feel is safe and then set for ignition cut, fuel cut or both. It pretty well kills the engine when it hits and you WILL let off.....
Keep it a little above your max tuned boost setting to keep from hitting it. If your map bins go to 200 kpa for tuning or your wastegate is set there set it for 225-250 for a major overboost issue. It's not a rev limiter.
You also have a rev limiter you can set since a turbo engine. will go through the rev range quite quickly.

Rubenski- it comes highly recommended.

Clone- as always thanks for an awesome explanation.

Just need to finish up some flanges.

Boost cut is very important. Afr safety too. You have an ms3. Take advantage of the bells and whistles.

The TD04L-13T has an external wastegate and the spring is set at 6.0 lbs so it is an excellent pressure to start tuning with. You can build a cheap MBC with a 1/4 inch Tee and some parts or buy one. I built one following instructions on the internet and it worked well all the way to 22 lbs.

The nice part about a EBC is you can hook a switch to the ground control wire and cut the EBC off for fail safe boost of the stock wategate. You never know when you might need to cut boost and don't have the computer with you.
With a MBC you can get out and just turn the screw out if needed.

Update:

Got the TD04 on and plumbed.

Took it for a drive and according to my logs still never hit boost!?! My gauge showed 6 psi. But mega log viewer shows 1.2 lbs I’m at a loss?

Any thoughts on next steps?

Appreciate the insight.

Sounds like your map isn't calibrated. What sensor are you using?

[Schweg]

Innovate sensor from a PSB-1 gauge.

Milage 165
Max Boost 8 lbs

So after some conversation with Chip ( Thanks again! ) I got directed that my MAP sensor was set up wrong so after looking it was. I ended up traveling for work last week and had some down time so I cobbled together a manual boost controller. I am curious what the TSA agent thought when they found that!?! Got that little guy together and on last night and decided to take the bug to work.

Also on this trip took a look at some previous logs and set my Lambda delay to what I was getting in my logs.
Fired the Blue Bomber up this morning an let auto eat on the way to work. Also gave it the business to see whats what. Instantly fell on its face! almost felt like sync loss. I pull over an turned of over boost. Hit the road and saw 6 psi in the end of second!!! Got another light and a long loaded 3rd gear pull I hit 8 psi and held for a min then..... Falls on its face again. Im thinking it cause I set my AFR safety net. Thank goodness I listened to some wiser people then me! I pulled up my Duty cycle when I got in to work I'm at 137% !?!?! So happy I put that in place.

All and all a great day. I need new injectors but I'm looking to salvage another set as fun funds are at an all time low. The auto tune feature is mind blowing how quick it works and well too. Though I think I need to lock my idle cells so it stops trying to autotune there.

I also scored a complete PRO METH injection set up that I need to install, and new injectors as this whole boost thing is addicting.

You can't use low impedance injectors can you? I assume not if your running MS.

The manual for the MS3PRO calls out high only, I am inclined to think I’ll stick to high only.

I feel like I over bought initially I.E. turbos and injectors. The ones I’m running I pulled from the Hyundai I got my throttle body from as mock up parts. Till I realized that the LS injectors I have are way to short to run. I’m not surprised I ran out of fuel, just how quick it happened though is getting me.

8psi is ~154% over NA power. Add the fact that you are probably over rich in boost, small injectors show themselves very quickly.

[Schweg]

If I have learned one thing so far it’s that I know about 2% of what I should to be doing this! But it’s fun and I’m learning. Also I’m at around 11.1 in boost at least that is the target.

The scary part is it pulls real well up to that point I’m already thinking that if 8 is nice then 10 is better. Though driving it today I was blown away by how well it drives without boost.

Also I’m going show how ignorant I am.... what’s a normal VW temp? I saw 140 CLT (on a dub shop modified sensor)today after a 15 min 75mph highway run. But never any thing higher. Is that hot enough?
Intake temps where about 120-140 but it was 94 today with 70% humidity. Just don’t want to screw this thing up

Boost is very addicting so you have to be careful! I did the same thing when I first built my draw through. I was on the 6 psi wastegate for about 10 minutes before I was poking holes in the Hose trying to increase boost!
And if your ignorant, I am too. I was wondering what temps should be as well!
