Hnda Etr Blows...

do eeeet. My guess is it's simply the starting point of some over boost logic, and may require either a few more psi over that limit, or a time qualifier. It'd be great to see it set like 2psi lower than what you normally use.

What is confusing is why the pull showed lean in the first gear during the pull. I wonder if the meth was not working or if we had unmetered air entering between the turbo and MAF?

I didn't have any problems with the meth, and remember the car ran ok the night before on the older map, so I don't think there was a vacuum leak anywhere, or the car would have run like shit the night after install....

I don't know if we'll every really know what caused the blow, especially with the limited data I have...

It honestly sounds mechanical to me. You were obviously over boosting, and the ecu appeared to be doing what he could to stop it (WGDC was 0's in that log). I think either a boost line popped off, or something screwed up with he actuator. Not sure.

I was putting off reading this thread bc I thought it was in response to the would you suck dick for $1B thread. Sorry to hear man, good luck...

Well, after Xmas I'll be able to pull the PG K04 off the car and take a look at it... all the hoses (all 2 of them) look fine going to the EBCS though...

If anyone wants to buy the PG K04 & PTP WGA, lemme know

thanks!

The car is load tuned from the factory, so it has to allow for a lot of boost variation. Makes sense that boost limiting tables would be pretty soft.

Compare the two dynamics tables - load hits hard and early, boost is soft early then harder at extremes. I set a BOLO in my brain for "boost shit I never thought of" because I know there's things I haven't had to deal with in load tuning that will now show up with boost tuning. Today I put a modified load dynamics table in my boost dynamics table (the over side) to see what happens.

you should run the ebcs in 3 port mode. I don't know much...don't know anything, really...but I can help you start off with your WGDC table once you get up and running again...

But I don't know how many hands you want in your jar...you know? =)

I am starting to think my Grimm EBC is not working right. I have it setup in 3 port and my WGDC is still about the same as it was on the OEM BC. It is my understanding it should be about 50% less DC setup in interrupt mode...IDK

Fobio is yours that much less than OEM?

[Haltech]

Are your vac lines properly connected for the EBC?

[Dano]

I believe so.....it is hooked up just like the instructions on their site indicate... but it does seem to be acting like it is running in 2 port.

easy enough to switch things around and see if I can VTA my block. haha I would of course knock my WGDC tables down first.


maybe I'll try that later today or tomorrow...

I did the EBCS's instructions and started off 30% lowered WGDC (by applying M to the table)...it was way too high...spiking 24psi...I never beat it like that, cuz it doesn't feel right.

this wouldn't be a problem if your upgrade was just the EBCS, but with the PTP WGA installed, 50% lowered WGDC was still too much. so I said eff it...I put 0's on the whole WGDC table, ran spring pressure, and were holding 18PSI...so I knew my preload was higher than I wanted by 2PSI, as I wanted preload to be 16PSI...oh well...

tuning from spring pressure, you first didn't have to worry about spikes, and I was also able to try a few things out without worried about blowing.

once my load curve/spikes were understood and contained on straight spring pressure, I then bgan to up WGDC to hit my boost targets and increase my load curve a bit at a time.

here's my current WGDC table:

[Dano]

oh..I forgot about your big WGA spring so that will skew the numbers for sho.

I may just have my WGA preload down to like 11-12PSI and just need to add a bit more preload so DC isn't so high.

thanks

Edit: just looked back at my WGA test logs and it is cracking at ~12PSI so I could go 1 more PSI maybe but IIRC 12PSI is about what the OEM K04 WG cracked at back when I tested it so IDK.

Dano, when I installed my Perrin EBCS in 3-port on the stock turbo I didn't change the WGDC at all and it worked perfectly. When I switched to the BNR, I had to set the table to 25% from 2250 up to begin.

[Dano]

so you lowered the entire table by 25% or set it to 25% of the original values?

I set the table value to 25 across the board after 2250...

O I C...gotcha!
