The MS6 Build-a-Beast is coming very soon...(Pics)

well there goes the thoery on unclamping everything.

my mods tbe/fuel pump/intercooler i just put on the ets3.5 car spikes to high 19s, holds 17-18, cuts out rinse and repeat. i am on the stock boost controller, no mbc, no ems, nothing. A/f ratios are as low as 9.3 right after the 1-2 shift. After that they hover in the mid tens to low 11s with low 10s high 9s after 6k. i beginging to think this car doesnt even need a mbc to reach and hold 18psi.
 
I say go MAF translator to block out the sensors, add some secondary fuel injectors, and tune them with a Megasquirt.

There is no way to tune the DISI with a current standalone. Not unless you have an Electrical Engineering degree and build your own system.
 
Hmmm, I wonder what it really spiked to. Most gauges can't read a spike's actual peak, it happens too fast, especially with a small fast-spooling turbo. I don't know alot about the dashhawk, or how well it reads boost, but it'd have to take ALOT of readings per second to acurately read a boost spike. That's why I like the e-01, it doesn't allow spiking if your settings are right. AFAIK, spikes with this turbo are pretty much gone with any kind of boost controller. My theory is based on the map reading something that correlates with the maf and rps. If it spikes, it obviously won't. You're seeing more boost because the ets has like .5psi pressure loss, whereas the stocker is more like 3-4psi according to cp-e. If you saw 15psi before the ic upgrade, the turbo was actually pushing 18-19psi. These turbos are so damn overworked from the factory, it's no wonder they're going bad so early for alot of people, and probably why they spike so easily with the stock boost controller. If you can get rid of your spike and still get fuel cut, then that would deffinately prove that won't work. However, I still think a scaled map would be much better than a clamped map with a car this finicky.

dashhawk takes a reading every .28ms. The boost cut happens about 2 seconds after the spike when the car is holding 17-18psi
 
That's wierd then. I'm hitting 18psi all day long w/o fuel cut at all, though I don't have an upgraded ic and I upgraded the other pump. I wonder if doing an ic would bring it back out for me. It wouldn't make sense though, cause I'd back my boost controller off to make up for the lower pressure loss, so the readings would be pretty much the same, it would just get there faster.

BAD NEWS

Today I pulled my car out of the shop where it was being tuned. My tuner gave up and told me that he could not figure out how to get around the fuel cut/ throttle plate issues. He told me he would look into it longer but it would be at a high cost for hours of R & D.

The other day I gave him the number for cp-e (to get advice on how to solve some of these issues) and he spoke with J Gartenhaus. My tuner told me that in a nutshell CP-e pretty much told him that they dont tune these cars and they dont have any advice on how to tune my car. I dont understand why they would say that since they engineered the standback.

My tuner made 300whp at 12psi on the dyno. I took my car out on the street today and it was hitting 15psi and the car was stuttering and popping. So im currently looking for someone to guide me in tuning my car either myself or with someone who actually wants to tune it.

Not trying to flame here but didnt CPE say they made 350whp with meth on a speed3 and a standback? Who the hell tuned it if they didnt?(uhm)
 
CP-E them self don't tune cars, but work with a nearby shop, if I am correct.

If you woudn't mind, I'd take a what... 3-4 hour drive down to MD, stay a night or two, if you get the time, and haev hat shop tune your Speed6, as they have had a Speed6 on their dyno dozens of times, many times with dadasracecar on there.

how are you measuring boost. A guage or are you actually datalogging it with something.

I've got a full sweep gauge with peak recall and warning light, and the e-01 logs it as well. With the e-01, I can play it back and check the comanded boost against the actual boost. It's a pretty neat boost controller. If I get an e-manage, I could tune the car through the e-01. The e-mange can do everything the standback does plus a couple variable auxillery controls. The e-manage ultimate does even more.
 
dont kno if this was covered before, but could it be possible that chris is maxing out the stock injectors? does anyone kno what cc our injectors are? just because he has the upgraed pump and the fuel is there, doesnt mean that they can throw the fuel. i dont kno that much about tuning, and this is just a thought, but if you look at any car that goes bigger turbo, they next mod the do is bigger pump/injectors/rail/fpr etc. when i ported my n/a rx7, i had to upgrade my injectors from 460cc to 550cc, jus from a street port. i kno this is a totally different situation, im jus giving an example. like i said, i dont kno much about tuning and im pretty much a noob, jus tryin to help out.

thanks for your input, and it is definately a logical option, but due to others testing, i (dada can affirm this) am pretty sure the injectors have plenty of playroom.
