I had been holding out on shipping out until I had more feedback on the new boards and was sure there were no bugs or issues, but unfortunately, feedback has been terribly lacking. There are currently 15 boards out in the wild, and there's only two people I know of that have actually installed them on an ECU.


It would be helpful if I didn't hear from you months apart at a time. As I explained two months ago, I don't know which address the old shipment went to since it's been so long, and I asked you to PM me whichever address was current, but I hadn't heard anything since -- prior to that exchange the last convo was from March where we discussed some KS roms and I was trying to track down where the original shipment went.

The project would have been done a long time ago if even a single person would've provided useful feedback... It's kind of difficult to accomplish much of anything when I don't hear from people for months at a time.

 

I am still ready and my affordable shipping option is still on, hit me on email

 

I was hoping to have some more feedback and things more tested before shipping more of them out, but I guess I don't have much a choice at this point. I'll shoot you an e-mail and we'll the ball rolling.

 

I might have to make a jumper harness and convert to an S4 ecu for the mean time.

 

How can I get a hold of one of these boards?

 

Finally got all the bugs worked out of the car on stock ecu. Will be working on getting my board installed to do datalogging to ensure proper operation as quick as I can

 

Any feedback yet? Very interested to see where this project has gone I would hate to see this project fall apart with this much work done so far.

 

I finally got board in mail (long story), now its with ECU at my friends for final install.
Then i can start testing out (if winter wont prevent me from pulling FC from storage

 

you so lucky.

 

Any update ?

 

sadly, ECU board from SonicRat would not communicate with PC (driver would install, but no connection) and we have been stuck at that point since i tried...

 

any updates with this? I am going to be getting my fc on the road soon and would really like to help develop this as well.

 

nah i'd say this is a dead stick, i went ms3 pro.

 

its not completely dead, James is making some progress afaik..
i am not, since i dont have s4 to play with right now (sold it few days after getting beta testing board ready )

 

I still have a stock s4 NA i'd like to test with and try seeing if I can make a 93 octane tune and squeeze out a few ponies

 

Please let me know if this project could work on my JDM N341 ECU. I now have an extra I could send out.

 

Given there's been no real updates on this in over a year (and the last word from SonicRat was closer to two years ago), I'd suggest you're best to look at standalone options if it's tuneable you're after. If you were just looking for a replacement ECU, used ones are available, eg https://lucky7racing.net/collections...-computer-n341

 

why bother with the JDM ECU.... the USDM ones have wiring diagrams actually available and your forehead will be less bloody.

$80.... they could list that thing for $10 and it would still be there 5 years from now.

 

Just to clarify; the JDM ECU I'm referring to is my stock ECU. The car is JDM and all I was looking for is an eprom like the 1.7 from RTek.

 

What started out sounding like an amazing project, killed by people too lazy to install the part and log data?

 

There was lag time getting the boards and components together. By the time I got mine soldered up, there was a 2nd revision of the board. I installed it, with a new motor, couldn't get it started so I put my Rtek back in and it ran. After 5 years of down time I was just enjoying the ride. Shortly after blew my turbo up and locked the motor so I didn't have any thing to test on. Also, if I recall SonicRat had gotten busy with some work in his real life and couldn't support it at the time I was ready to go. So, bad timing for me, old hardware, and a working car ruined it for me.
Then I stopped screwing around and bought a Haltech sick of the limitations of the factory sensors/30+ year old harness.

I still have the ECU I modified wired up and collecting dust.

 

I've received a lot of interest in this thread by email / facebook over the past year or so since RTEK has closed up shop.

RevinRx7 here is correct in that I do not own an FC, so I had no means of testing the development other than on the bench -- this forced me to depend on volunteers, who often had other things going and/or weren't immediately available to install and provide feedback. Consequently, things moved at a snails pace and it was often difficult to get consistent feedback or troubleshoot problems when I was nowhere near the car to be able to debug. So, I basically just tabled the project and took it to email/facebook and worked on it as I received feedback. The hardware has changed quite a bit from those earlier versions to simplify installation, reduce costs, and make firmware management a lot easier. Eventually, I was finally able to wrinkle out all of the kinks. I believe there are at least two cars currently running on the boards and firmware I made. Their feature set more or less mimics RTEK, except with a tad bit more adjustability. I'd long since lost interest in the thread as there wasn't much community involvement here outside of a couple of volunteers who I usually just contacted via facebook / email and I've been too busy to be able to build boards by hand / help people with installations and so forth.

I have nearly all of the vital S4 NA/TII ROM decoded and a chunk of the S5 TII, so I can help people create custom firmware images if they want to flash ROMs to install like RTEK used to have. Outside of that, I don't see myself mass producing boards and pushing the realtime build outside of just friends / acquaintances unless someone knows of a cheap fabhouse that can both print and assembly the PCBs.

 

Hey boss,
glad you're back. Thought this was a dead thread. I've been working up to do this sort of thing. Hopefully I can try to do this mod when I rebuild my engine this spring.

 

Sonic,

had a good day of weather and got the ECU pulled from my car. ECU is an N370. What would I need to do/study on my end to catch up and prepare for doing this mod?

 

N370 is a S5 TII ECU, I believe -- what would you be aiming to do? I haven't done a whole lot on the S5's outside of the basics -- so while you could put the realtime board on it, it would be a bit limited by comparison to the S4.
