tactrix will work with techstream for real time logging

I wish I would've known this a long time ago lol... I just figured it out and man that makes things a hell of a lot easier.


I wish we could use the data for a GUI to display as gauges...


It looks like the map is also including atmospheric and that it showing 5 psi is actually like 10 of vacuum?

I suspect techstream uses some form of generic request for ecu data as i have quite an old version and it will still work on cars with later calid, hence my suspicion its using standard obd calls, rarther than like tactrix wich uses direct ram addresses that change with calid.

Its possible you may be able to sniff these requests and then use something like torque.

i have not bothered as i have ecutek and it will log everything anyway at good refresh rate

I'll look into that and see what I can do.



I had been looking at the torque pro app and it looked promising, but people didn't seem to be able to log knock with it.


I can see virtually EVERYTHING in real time with techstream. I may use torque pro for the gui for some gauges like MAP, oil temp etc... and then use techstream for live tuning, well not live tuning but for live monitoring for the purposes of adjusting the tune.

I'm hating that I have to pay $400 for a tune and $300 for a license for ecutek. I have the ecutek dongle already but am having second thoughts.

Can I use the ecutek dongle for ecuflash? If not I can get a tactrix cable. Just wondering, is it worth trying to tune myself? I would just start out with very low timing until I got the fueling right. It will be on an AVO turbo 2013 frs

To use ecuflash, you have to use an openport. But an OP 2.0 can also be used with Techstream, and Evoscan...for other things.

Open port 2.0? Is that another cable?

How hard are these to tune

How hard are these to tune using ecuflash? Is it self explanatory or is it not something any gear head can do? From my understanding at 10psi on 93octane you want it to be around 11.3 AFR. Isn't achieving desired AFR as simple as plugging in what lambda you want the car to be at and making minor tweaks throughout a table to keep it steady? I would just start timing low to be safe and add that after fueling is done.

It's an odb2 dongle, google it. Not as user friendly as an oft but it's easy if you're careful.

Tuning a boosted car from scratch is not easy

The tables you have access to in romraider ecuflash brzedit or ecutek are similar, ecuteck has quite a few extra features as their software also includes rom code patches to add extra functionallity and features. The other systems just give you access to read edit and flash the existing rom tables.

I would not recomend anyone trying to tune a turbo or sc car from scratch unless you are quite experienced with tuning.

if you bought say a sbd kit that comes with an open base tune, it possible with a bit of reading you could tweak the base tune to run a bit better. Although fiddling first time with a 10 psi tune can be dangereous.

maybe cut your teeth doing some NA tweaks then maybe work up to boosted, but id suggest you tread very carefully and start with a base tune and kit like the sbd, and maybe the lower boost 7 psi version

the logging is were your likely to run into issues as with tactrix its fairly raw and you need to know ecu ram addresses.
you might be better buying an open flash tablet or brzedit or even ecutek as you can make your own maps with ecutec

and talk to the speed by design guys i think it about the only opensource tune and matching kit arround. Dont try and use the tune on a different kit whole kit turbo piping intercooler wastegate the lot must match else you risk serious engine damage

edit: I wonder if they assigned the same issue number as mine to your request.

Last response was April 22nd when they said issue was fixed but were rolling some other improvements into the firmware upgrade. Estimate of one week at that time. Chased them on May 5th but no response yet.
I haven't checked to see if they fixed it but didn't tell me. Not sure if this is easy actually!

The tactrix guys REALLY need to do something about this... People having to months without having logging capabilities is PATHETIC... I've gone just a couple of weeks without it and it's driving me insane...

Summer is coming and ambient temperatures are about 20 C (86F) right now - perfect conditions!!!

Being left without logging for nearly two months was not acceptable any more.

Two days ago I finally gave up and bought a Brzedit license. Was very angry at first having to go that way... but...

finally being able to use live logging made me not to regret it.
