Any issues with the 93 tune? It appears most of the issues arise from the 91.

I can't speak for everybody, but I have no issues with my Attache (knock on wood).

I hope to be able to tell you soon enough but TTurbobullet and I cant get a response back from Eric or Ralph since they are at that meet.

I was hoping to have it this weekend to install but it is looking like it wont be for another week.....

cant really say its 91 octane as I tested the maps locally on a mix of 89 and 93 octane. I think this may be a case of ethanol content in the fuel. I already know where I have to make my changes in the maps for these tunes as I dealt with a similar issue on my car at the track with a toluene mixture which coincidently has a similar stoich to ethanol. Ill make the neccesary revisions in my maps and all should be well

ended up removing the dp's going back to stock, sent back the attache to get the standard 91oct map flashed. get limps with power loss just about everytime immediately after wot or close +60% throttle.

i have an manual 08 with 8/07 production running shell 92oct (northwest) with the standard MT 91oct map. after numerous discussions with eric he wanted to try full time hot for power vs. switched to see if that would alleviate the issues. he mentioned they had similar issues with another 08 which he thought had the new dme and running full time hot would be a workaround for sensing the tune. i am 99% certain i do not have the v81 dme nor do i think that would be a fix as the limps occur after warming up the car @ wot. after those discussions we agreed to send back the tune once again and swap it out with another.

this is only the second time i have shipped the unit back and this method is already getting old quick.

my biggest complaints with this tune:

1. lack of capturing datalogs & monitor
2. no option to bypass with plugs, etc
3. no way to flash maps without shipping back

with that said, eric has made it apparent that all troubleshooting should be left to his engineer which most likely goes hand in hand with my complaints stated above.

i don't mind having issues and understand the fact this is a new tune however, shipping the tune back everytime is not going to be feasible in the long run.

#2-3 should n ot be an issue from this point forward as Helix plans to have a few attaches in circulation for swapping out so no downtime...#1 can be handled by getting 1 of many datalogger/obd-2 computers such as actron or the OBD portion of vag com Hex-Can.

+2 No issues here either. '08 auto (10/07 build) on Shell 93, stock other than attache. No codes/no limp modes at WOT.

Both you and XLR8MF are having the same issues and both are running shell 91 octane fuel. when you both get your attaches back first try the revised map on the shell fuel (it should be fine) but also try it on another brand of 91 octane fuel and report back to me.

That is not a problem. i am willing to help give feedback. I personally do not think it is a octane quality issue but you are the engineer. TT, I have questions for you:

1) How fast will the turn around be on this unit?
2) Are you sending me back the same one or a new one?
3) You mentioned you know what you need to do, will the changes affect the HP and torque?
A do not want a revised tune that decreases power.

I still have my Forge DV's, Riss Racing DP's Borla exhaust and Gruppe M intake on Shell 91 and the car runs fantastic. Not one problem. Yes I am running O2 sims. I only mention this so that the other member having the same problems may want to keep his DP's as I think they are not responsible for his problems.

i'm not certain the issue resides with octane as well but definitely worth a shot. its sounds more feasible then running full time hot in regards to switched power. we use shell 92 octane here in the northwest which is pretty much the best fuel in terms of quality.

i removed the dp's as i experienced 02 related issues and did not want to run 02 sims w/ hfc cats which in turn triggered multiple limps (non powerloss, same as peeps running catless w/o sims) with and without the attache.

it was also easier to isolate further issues by removing the hfc dp's and going back to stock. after all said and done, i get constant limps (obvious power loss, wastegates open) with only the attache @ wot.

i came to the conclusion that either the standard 91oct map was conflicting or i had a bad attache (hardware) all together as i went through installing/unistalling that harness at least 6-7 times to rule out installation errors. on the bright side, i have the install down to 15-20 mins once i get access to the dme compartment..

anyhow, i was told numerous times i was the only one having issues with the 91 oct map even though they stated there were a few others running it which was indeed frustrating. i know i was one of the first non east coasters (non 93oct maps) to get the attache so i figured it was only a matter of time before others would experience issues running 91-92 octane if that is the case. i just hope the map changes don't severely nerf the power. it was a huge difference between the dp map and standard. i look forward to testing the new map.

TTurboBullett,

I have sent you a couple PM's! How do i get a switch working so i can use my stock map.

its pretty simple, you install one lead of the switch to the map wire (i think it was orange, its labeled) on the attache and the other lead on the switch to ground.

flip the switch (closing the circuit) triggers the second map i believe..

Come to think of it we did run into an issue of a hiccup under peak boost in Mark's car when we hit WOT. It ended up being the Bypass Valves. Once we put in the BOVs with a specific spring tension this issue went away. Sniz is coming over tonight and we are going to see if this is in fact the same issue. FYI Sniz also has the Forged BPVs. Regardless of the issue we will seek it out and destroy it. (oops sorry I need my COD4 fix)

bwahhah.....I was up til 1am playing COD4 online. Its so much fun on my 114" HD screen and way to loud speakers . my screename there is sniz08

back on topic.

My car is running great. I will be meeting up w some of the Helix guys this evening and doing some testing. As of right now I am running the lower psi springs in my Forge DV's. I want to switch to the Yellow 12-15psi springs, but have not yet. I was the 1st person in the US I believe to receive the new Forge DV's for the N54. At that time, they were recommending the lower tension spring for psi up to 15psi, so I didnt swap the springs out. Now they are recommending it. There may be the possibility that running the wrong springs is what is causing me an issue. I hit a limp just as I let off WOT at the end of 3rd gear. I will say though....the car gets to the end of 3rd gear AMAZINGLY quick. Power everywhere, love this tune!

Dude COD4 on a 114" screen here too with Dolby 7.1 baby I can hear them walking around me. I am itching to play since I been stuck in Chicago tha last few nights. COD4 name = LedChucker

ha...nice! I'm running 4 powered subs in the front. 1 dedicated 2000 watt Velodyne 12" and the other 3 are in the front towers and center channel....its insane. Gun shots and explosions hit you in the chest. I love it.

You can hear them walking around here......kinda freaks me out. I dont want to move but you gotta see where they are!

Hey Sniz, I do not think it is your springs in the DV's because I run the yellow from day one and never had an issue with them. I agree how fast the car is but until the limp modes are gone I cannot say it is great. i am sure it will be resolved. Do you have the 91 octane or 93 map?

TTurboBullett: can you answer the previous questions? Thanks

[e.n335]

The Attaché seems to be a great piggyback. But now, where the units get widespreaded, a map upgrade by downloading the map from an internet server and installing it using a laptop would be a great advantage. I'm pretty sure the efforts for an Attaché map loader software would not be too high. In addition such a software would free up ressources as well.

My 2 cents.

i'm running the 93/dp/fmic map and the 100/dp/fmic map. The second map I have not tested yet.

are you getting your limps right at redline when you let go of the gas?

I'm running the lower psi springs right now.....fingers crossed the higher psi springs will resolve my small issue. I heard they had a similar issue to mine when testing the attache w/ the stock DV's. After switching to a better BOV designed to run that amount of boost the issue went away.

from what I'm seeing boost is peaking at around 14.2psi and holding steady in the high 13's throughout the rev band.

my gauge saw a few spikes just over 15psi on upshifts that I did see when looking at the gauge. The peak recall function was the only way I knew it saw 15.2 and 15.4psi on 2 seperate runs.

I'm happy w/ these boost levels..I dont want a tune that is pushing 15psi constantly. If I get the power I want out of a high 13 - low 14psi tune i'm happier than a pig in sh*t.

I would be happy as well with the speed I am getting for this boost range. The limp mode I get is in 4th gear at 6500 rpm at 120 mph. I have an auto so it is against my religion to let off the gas before redline!
The bucking occurred in 3rd gear at 5000-5500 rpm.
