Tec3 issues, looking for input

IMR-Merlin · 05-22-2015, 12:24 PM

I am in the finishing stages of my project and I have an issue with Tec3. Injectors don't seem to be flowing any fuel on the entire right bank of cylinders.

1-2-3 all have fuel flow, but 4-5-6 have no flow from the injectors. I am getting 14.1V on the hot side of the injectors and when I did a pin out on the plug to the Tec3 all the wiring is correct. Is there a way the right bank isn't getting fuel pressure? It looks like a common feed rail....

if you swapped an injector wire from the 1-2-3 bank to the 4-5-6 bank, wouldn't that allow you to isolate it to a fuel pressure vs. Tec3 or wiring issue?

It's def a Tec3 issue, all injectors are getting 14v to the hot side, but the right side bank is not pulsing. I did a pin out from injector to Tec3 plug and everything tests fine, so either I lost the Tec3 or there is a software issue

Single or dual plug?
You may want to compare your initial software settings with mine just to eliminate possibilities.
Tec3r tune files?

Is this a new Tec3?

Ok, figured out the fuel issue. I am not running full sequential (no cam trigger) so they only use 3 channel instead of all 6 injector channels. She runs on all 6 now and purrs nicely.

Next issue is I have a ton of EMI that we are trying to figure out. I can get the Wintec software to run great till we fire the car, then it crashes the GUI on Wintec and kicks us out.

Using a laptop or a PC? If you don't have enough video card in your laptop the video GUI will crash, usually while trying to run 3D mapping. Try running in matix maps only.

This is crashing as soon as engine starts running. Friend is using his tablet that supports data logging on his 034 software.

Where is the ECU mounted?

IMR-Merlin · 05-23-2015, 04:07 PM

Passenger floor.

I hate windows and refuse to use anythng widows based....

That being said ....Electromotive does not support anything else

I got a laptop with newer windows on it and had wierd tuning issues ..I could not do live tuning
and had wierd crashes ..no logging ..would not save changes

I got an older lap top and loaded windows XP and did Zero updates and I NEVER connect to the WWW with this lap top ...I use a USB to transfer stuff like Wintec and a USB to serial driver

the lap top/wintec has been solid and ..I can do Logging runs , live tuning ect ...

might be your issue

now to get them to support Ubuntu before I switch to Megasquirt ....

IMR-Merlin · 05-23-2015, 04:23 PM

I have an old thinkpad coming that has XP on it. I am planning to DL Wintec on it and try that.

i'm NOT a fan of Electromotive ANYTHING.. Not trying to start any wars or anything like that. I just am tired of typing a history lesson of all the issues on the many cars I have tuned over the last 25+ years using their products.
I have been a loyal DFI customer for 20+ years. I have never had any issues from DFI 6 (DOS) to now (Windows based from windows 95 through 8.1). But not many people in certain marques care for them.
I have tuned Haltech's. Big Stuff, Motec, LINK, DTA the list goes on. All systems have their pluses and minuses.
I'm thinking your problem is due to a bad ground or possibly something in the new harness...

Older laptop is the key for The Tec3r. At one time I hated the Tec3r but then I got the PLX wide band installed and my son and I tuned the car in one 400 km session live on board followed by some data logging at the track. Stay with it-worth it in the end.

Running a virtual operating system is a much easier way to do this if the program won't run on what you have.
No need to seek out XP, Linux, or whatever.. with this program you can run anything on anything and there's no way to get a virus with it.

A professional IT guy turned me on to this one and it's free with no adware or other junk.

I'm with you 100%, the Tec3 is dated for sure, it's buggy, but it's what I have now. I am thinking of going to a Vems unit at some point.

I would go 034, but then I would have to build a complete new harness as they run positive trigger for everything.

If you need an old laptop, I think I have a old Dell with XP on it I'm not using anymore. I can find it, dust it off and wipe it with a fresh install if you need it. LMK

IMR-Merlin · 05-24-2015, 06:07 AM

I just had a friend dig one out of his daughters closet. XP with service pack 3 on a 2.4GHz with 1.00GB of RAM.. this thing is gonna fly... LOL

GJF · 05-24-2015, 02:02 PM

Maybe the coil packs being over the transaxle positioning them closer to the ECU might cause the interference??? you have a O scope available by chance?

I went from an USB2 connector computer to a USB3 connector computer (no they are not 100% compatible) for my TEC/GT and could not even establish communication.
