Scott suggested that maybe I have a boost leak but I was tugging at my intercooler pipes and no budge. I'll try re-tightening them down just in case.
PM me, if you have not figured it out, I will be home on the 22nd. Maybe I can help you out. Assuming we don't fry anything on my car.

I may have found this-- It happened to me using an .msq from 029v on Hi-res. the same thing 'might' happen loading a hi-res .msq into 029v. not sure if that is the case but here are the details... see post 89.

!! Thank you FoundSoul and Saboteur, and everyone else in this thread. Just have to wait for the boss man, "Scott" to chime in and see what he says since he preloaded everything for me.

Matt, this is the MS that we had trouble loading the software in. I used the same map i load everyone with and made changes from there....029v....very odd.


i guess i can make another clean map for you Nick and you can reflash the firmware. ill send you an email with how-to.

Actually it's Jerry here

it may not be the same issue I saw-- but the symptoms sound at least similar. The circumstances are a bit different though. if your map was built on 029v, and he's running it on 029v, that may not be the issue. He may need to plug the unit into another car to rule in/out the MS as the issue at all and then go from there...

Depending on how Scott did your ignition mods you could send it to just about anyone. If they are the same as DIYautotune has them shown then even I could test it in my car. If not you would need someone with the correct harness to test it for you. Scott should know who can most easily test your MS.

Nick if you wanna send it back to me and ill test it out on my car and make any corrections as needed. Im trying to think of who is in NC that has one....

i used the standard ignition mods, but whomevers ride it goes on needs to swap plug wires, 1&4 with 2&3 before you start it up.

subscribed as I'm having very similiar issues...
Still troubleshooting a few things with Scott, but very interested to see where this goes...AND figured I could share as well considering we seem to be after the same solution...

Aflac, how does you car behave GETTING to the 3k rpm "dead zone"??
Does it seem perfect, somewhat underpowered/sluggish, or is it completely lazy and struggles/takes forever to even get it TO 3krpm, then wont go further???
I ask because mine behaves like the last description...
I need to re-check my timing, and lean out my fuel table, and redo the easytherm as it seems my values may be messed up...after that I really dunno...
I've already disabled any settings/cuts that are rpm based, am running a open DP, and did a few other things with VERY little improvement...
Only improvement I saw was that my problem was 2k rpm, now I am close to 3k rpm....but no improvement in any other way...

Let's share what we've troubleshooted, tried, etc so we can hopefully get ideas form each other...different strokes for different folks, but could also be the same thing...or at least something similiar...

***it should be made clear that I'm not trying to say I'm unhappy with the help Scott's been trying to get me...he's been giving me alot of support, and it's obviously something hard to figure out without being present. Just figured it'd make good sense for us to pool our efforts!

For some reason im not getting emails sent to my inbox when someone responds to my threads anymore so im sorry for the delay.

To answer your questions and update other people:

I sent and received my MS back from Scott. He gave it a look and made adjustments but im still running into the same problem. So that leaves the problem on my end of the spectrum. Im re-tightening all of my intercooler piping again and see what happens. The car can rev past 3k at idle but won't under load. Im not running a AFM, maybe the wires are crossed up? I'll post pictures just in case i missed something.

I agree with tvalenziano, Scott has been nothing but help with great feedback.

Guys I basically resolved this issue on my car...I think the rest is just tuning as its really rich throughout and is bogging some..but a BIG improvement..


Aflac, if u got the EBC mod done by Scott check the Boost Kpa Targets table...I inputted the exact table that were in the instructions & it was 100 for the 1st 2 columns then 30 for the rest. I just copied it since I didnt know what it meant...After going back to my original MSQ & tables (i was plannign around with it) I also put all the values at 100 and it made a big difference...No longer feels like it CANT go faster/higher rpm..just feels like its real rich (afr confirms) and being held back...

Also make sure the Boost Protection is set to something reasonable that wont hold you back for now...I used 16psi..

**OF COURSE u should listen to Scott and make sure doign any of this wont mess anything up, I took a short drive and made a BIG difference...I did not/would not drive hard, or long...Just enough to see if it feels better..

GL man!!

Thanks man!
Hope it works!!...I'm really anxious to see if this helps!! Please post the resuts...(Advanced-->Boost Kpa Targets Table 1)

I dunno where the option is to select whether to use table1 or table2 (like w/ VE & spark), but should be set to 1 on default i guess...

GL..waiting to see result post!

I don't really understand why you guys are even bothering with the boost KPA tables. We're not even using closed loop boost control so that table is irrelevant.
You should be messing with the duty cycle tables.
Even if you were trying to tune your KPa table, why would you set it all to 70 instead of the actual boost levels you wanted to see that that rpm/tps?

I don't touch the kpa table, im just posting what it was preloaded with as requested by Tony.

Attached a picture of the current preloaded boost duty target table. What do you think?

Looks like a normal EBC table to me. At least there is nothing wrong with it. Keeping the wastegate closed longer will help it spool faster. Keeping it at 100% duty until you reach desired boost, then drop it to the appropriate duty to hold that desired boost.

It has to be something on my part since I recieved back the MS from Scott that was tested on a 94 boosted miata and it revved fine.
