    Have a ECU which is firmware 2.37 and tune 05 pr. screen.
    Can it update it with EZ updater 03 which i can download from Fast homepage?
    Think my tune 05 is newer but can i do any harm if i update / overwrite with updater 03?
    Reason: system is unstable, se my other post in forum.

    Edit: Tune 05 is maybe not the same as update 03, has anyone update with 03 and if yes which tune do you have?

    Seems I read somewhere on these boards the software available from the downloads page is version 2.38, tune 003. Even if it isn't newer, it shouldn't hurt anything.

    Software 2.38 tune version .003 is the newer version reflected here: http://www.cpgnation.com/forum/threads/old-ez-with-new-handheld-is-possessed.26639/

    Your earlier software may well be the cause of your problem. Install the newer 2.38 FAST download #3 using the instructions. Software and instruction toward the bottom of the page here - http://www.fuelairspark.com/fas/software-downloads/

    Tried to update today but i get this message "This unit has already been updated" so either is update 03 to old (you can't downgrade ECU) or communication with ECU isn't working.
    Will as Fast say in instruction try to tinker with the USB-serial adapter later.
    NB! if i power ECU off i don't get "This unit has already been updated" message and i looks like my laptop can't find ECU so i think communication is ok.

    238/005 cured all my problems with 238/003. Sure would like to know what they fixed in 005.

    I have now tried to tinker with my the USB-serial adapter and i keep getting this message "This unit has already been updated" so either i'm doing something completly wrong, not an option i my eyes :), or you just simply don't can downgrade FW/SW in ECU.
    Just to do something i tried again with new handheld and..... same story keeps rebooting from time to time and stalling engine every 2 or 3 time its rebooting.
    Have been writing to Fast one more time....... same result no answer!, tried to write to Comp and hurraaaa got an answer asking for part number, responded to that and then...... nothing but silence.
    Must admit i'm not the biggest fan of Fast right now so have been looking for some other EFi and i think i will go for a Holley Sniper system instead of Fast.

    After a few days i got answer from Comp that it must have something do do with my ignition system or battery or...... totally ignoring that my sytem has been working for 2 years with out any problems and that my problems started when connecting new color handheld.
    After some mailing to and from and explaning that i live in Denmark in Eu there final answer is:
    "We need you to send the ecu and handheld to be tested."
    So no software via emal or download link nor any updating of software download on Fast homepage acording to Comp.
    So a Holley Sniper ordred an then someday when a friend goes to US on holliday i hope he can be the postman and that Comp /Fast can fix it while he is in US.

    I am still waiting for an answer from FAST.

    It makes you wonder why they ignore customers.

    They are active on instagram - so at least some of them are working......

    Hello
    After a long time, it finally managed to send ECU and screen to Fast (via CompCams) and now after they have had it for about 3 months it has finally come back.
    But there are no papers with at all that tells what they have made or not made so do not really know if it works now.
    So question: can you only put ECU to + and - and similar to screen and then read Sw and tune version on screen.
    Thanks in advance.

    I wouldn't. I would only fully connect all the ECU cables, and handheld, correctly before turning the ECU on to read the screens. Otherwise, you risk damaging the repaired ECU. FAST hasn't been known to return un-tested unrepaired RMA components.

    OK
    The reason I ask is that I can see that ECU has not been separated.
    If I put it all together on the work desk except the gasoline part then should it be ok?

    In your case, there would have only been software changes. So, the ECU case would not have been separated. The screen will show errors without fuel pressure. Anything about the software flash update will be printed on the ECU.

    OK Thx
    My ECU looks exactly like when I sent it over to Fast.
    There is nothing new printed on it at all.

    Someone just re-flashed it. They've claimed they use the same tune program but have to update using a later version number for it to be accepted by the ECU. It should work fine now if you want to install it again. The Holley Sniper you installed may be a bit better than the EZ EFI 1.0. I would just install the EZ EFI 1.0 to something else.

    Has got checked version on FW and Tune version now and ECU has been updated.
    Current, after update is EZ_FW 238 and tune version is 005.
    Before updating, it was EZ_FW 237 and tune version 005
    Firmware on handheld is the same as) 0.1 (so no update on it, there is certainly no update yet.

    So the conclusion must be that if you want to upgrade to color handheld then you may, but not necessarily, get problems if you do not have FW 238 and tune version 005.

    Finally in this story, I have to say that with my experience of Fast and their total lack of customer service means I will never trade with them anymore, there is only a bright spot in this case and that is, they sent my stuff back free of charge for me and in the right way so it does not cost me anything in customs and VAT here in Denmark.

    Over and out
