Hey guys,

 

I cant find the thread I was reading where you all were talking about the PSG being the actual 65HP limitation /w the smarty or non wire tap programmers on the vp44. I got interested and I found a lot of info out there, primarily some french guys where I used google to translate. showing clips to read the 24 series eeprom with 3M clips. They eventually caught on that you could put 5v to one of the legs on the chip and make it no longer read-only (this is common, and I suspected it). Because their forum is invite only I couldnt download their diagrams or documentation they created. I also found some Indian website that showed how to read/write to the PSG /w an arduino, including wiring diagrams and so fourth. I cant find that in my history now either, but its in there somewhere. Anyways, here's the french lads that tackle read/write to the PSG. Every time they say "code", i think they mean "encrypted". I tried to join the French board but it seems to be invite only.

So bottom line is, I think we could read & write from the eeprom. The question is who is going to modify the code. I know somebody was saying it was encrypted, and that wouldnt surprise me, but it sounded like the french lads were pulling it encrypted. If we could find out what it's encrypted with, and we rented some Amazon AWS servers, run a linux shell to brute force it or rainbow table it, whatever it be. I have to guess that 1998 encryption schemes would be very crackable these days. The Geforce 1080 is no joke /w 2x the power of the 980 and half the power consumption. I saw 3M connectors to read from it without taking it off the board. It sounds like they wrote to it by enabling 5v on the correct pin/leg of the chip (I dont know which exactly b/c I couldnt get to their attachments), but soldering a new one on /w a fresh flash is something I imagine could be more convenient. I did come across pin diagrams for the chip on either their site or another. I dont know if you'd have to take the 5v away from it after the write, but by the way they talked it didnt sound like it. Hard to tell through translation, though.

Essentially I recently became knee deep in this hobby. I have a 98.5 24v /w D&J motor built to 700hp spec /w CNC'd head on intake & exhaust, 62/68/0.80 + S475/96/1.32 twins, currently running 50hp inectors /w new Edge Juice Comp with smarty SO3 on the side. I have 120hp DDP injectors next to me that just got backfrom warranty, which Lenny looked at personally. The first time around Brian handled it. I've spent a lot of time fixing drive pressure and boost pressure leaks, I think they are 99% sorted based on the performance I'm feeling. I need to do another boost test leak. More on things: 5" down pipe, mishi rad & intercooler, banks monster intake, blah blah. Still only seeing 43lbs of boost. Without the wiretap I only saw 28 psi max on a brand new Industrial Injection VP44. After putting my old pump back on, that is wiretapped, I once again saw 43psi. This is what enlightened me to the necessity of having proper fueling. I'm so far into this VP44 platform now that I wont be switching to CP3, unfortunately. Got it all mated to a Firepunk Comp I in a ext cab LB chassis. I paid some guys to work on my truck and was so let down that I learned the hard way, the only way is to do it yourself.

 

I come from a background of computers and dirt bikes. My dad was a firmware/software/hardware engineer who came to the US from Australia. Due to him being an alcoholic I wouldnt waste my time asking for his advice, but once upon a time he was very smart knowing low level stuff like assembly (programming), layers to protocols, making PCB's, soldering them all up, programming them all up, etc. Credit card readers & bill acceptors seemed to be his bread and butter primarily. Also some assembly line stuff like productivity displays, etc. For roughly 20 yrs he worked solo as his own contractor. 

 

Perhaps this could lead somewhere? I'm considering sending back my II VP44 for a hodrod pump, seeing as my tapped reman VP44 that came on the truck is running just as good & better with the wiretap. I had previously bought the new std output VP44 from II as a method to troubleshoot a hard-start condition when (almost) eveyrthing else had been tried. Turned out to be a drive pressure leak @ the 90* hot pipe connecting the turbos -- I fixed it, and the truck starts as it should.


Sorry if this is in the wrong section.

  • they prob kill themselves after dealing with all the oddities of the electoronics.  

  • If you came into my shop to have a transmission built, with a 62mm top turbo and that large-housing S475 on the bottom, I would recommend a stock stall speed converter. I would recommend either a Goer

I never dropped the truck in drive, it was like something was wrong. I need to try your tunes bad, that is first thing in the agenda.

 

Do I flash your tunes to the module? Are they different all together from 2.7 or are they based off 2.5? I assume they are just "tunes" that will run under v2.7. I don't need a guide to figure out how they go on, but I doubt they get flashed like v2.7 did to the unit. Am I wrong?

 

I'm still unloading the trailer. I was 22 or 23k gross with a 28' enclosed and my last fill up was 257mi used 18.87 gal which comes to 13.3 mpg. Driving 55mph on third gen 17s at roughly 600ft elevation down to sea level, with the quadzilla rather than edge. I can't wait to get rid of the Lowend black smoke. With the trucks shift points up in the 2k range and no more stack shift after Firepunk bent the TV bracket at the trans to put a little preload on the cable / tv lever arm, and the low elevation, and the phenomial injectors from F1 Diesel, the truck is begging for some cleaner tunes to be a real street machine. Too bad it still has a hard shift every once in awhile. It's still a 1998 but she runs alright. Quad was on lvl0 whilst towing. I assumed that would retain stock timing.

the base flash is just hte 2.7 we have hosted here,  then you apply the custom tune to the iquad app and that tune writes the values to the base flasht o change it how you want it.  

 

I would ensure you are running the 2.7 I posted not to long ago.  when did you flash it last?

  • Author

Just the other wk right before I left. I left on like the fourth so I may have flashed on the first.

 

I just haven't seen an import function in the iquad app for the tune. I'm running the $50 Amazon fire tablet as a readout which I didnt realize didn't have the andorid app store. But app from phone to pc to Amazon fire did the trick.

there is no import button,  Follow the video

Very well, thx for your good work.

 

Pic of the rig just for grins. Almost as long as a semi.

Synopsis of custom tune import video:

The custom tune is a file type associated with the iquad app that when opened on your phone or tablet with quadzilla software, is auto imported & lands on a screen where the tune name can be set.

Hey man all I see are tow tunes and race tunes for large injectors. What's the equivalent of a twin  turbo large injector daily tune? Tow tune I assume? I like how u have the emissions tune on there. Thx for your contributions.

Just found the descriptions, jumped the gun." Large Injector Extereme tune"

 

Sounds like what I want. The thought of full throttle pedal capability off idle like the description says has me wildly facinated. I've never had that feature on my truck before. It had an edge jwa on it when I bought it.

Your large injector extreme  tunes run great, I'm very impressed. My truck no longer haze's white smoke bad at lights when it's cold. My oil pressure when crusing the hwy in 3rd locked at 1900-2100rpms 55-62mph is 54-60psi. I'm starting to think that's making oil seep by the seals in the turbos. John at Pusher Intakes reached out to bullseye about a rebuild kit and oil restrictor fittings and he came back saying the turbo uses a hard faced seal that uses oil tension to seal, so he doesn't think a rebuild kit will fix my problem. I'm surprised my truck smokes less with your tunes , given that the idle speed hasn't changed. Any thoughts? 

 

Ican still make a nice black haze as I take off if I'm not dainty on it, but when I'm hazing I'm making nice power. Im at sea level now, I saw the water today. I was squealing the tires quite loudly and ended up killing the motor from getting out of it too quick. Had just unloaded the truck in an effort to clean it and had no 19mm. Luckily stores were just a ten min walk away. Still the truck wasn't in a good spot stuck in a lane of traffic. The tunes are on 3 for now, they were on 5 at the time. After I get used to things and see what max EGT is and such I'll step it up. For now it's a lot of truck :) Thanks again. There's a slight stumble off idle maybe 25% of the time, perhaps when im real easy on the gas, but honestly it's incredible how well mannered and light the smoke is now. Seems like the rest of the tuners are way behind the curve. Maybe these old trucks are the ones people have forgotten about and not kept on developing, aside from Quadzilla.

 

On the Amazon fire the tunes file from the repository here is not a file type associated with the iquad app like it is on my phone. The open with menu doesn't have "other" like it would on a windows computer. I have a file manager app that I use to import the quadzilla app from the Android to the Amazon fire tablet, and it's open menu is long and exquisit, but even it doesn't have non-default Amazon fire programs. I'd have to replace the music exe file with the iquad app to trick it into running the iquad app when I select music or what have you. For now since I can pull up all your settings & Import the tunes on my phone, I can go the long way on my tablet and manually input everything.

 

Quadzilla, if your listening, why is there no Import or export button?

 

Also what's the deal with the data logging, I see export but does that export the last 24 hrs or? I don't see a start & stop button like the edge had. The stats it shows right now after I hammered around town today have to be off, it shows a Max of 1150 egts & 24psi of boost.

 

I must say Quadzilla if your listening, I have a 7" display and the power +/- buttons are quite small and hard to hit whilst driving.Same with the sensor icons, they're mighty small and the menu can be hard to bring up whilst driving. Holding them to see their description is a real task whilst in motion, too.
