TMAX-6th speed indicator not working-followup
I can e-mail you the Reprogramming instructions if you'd like or if you haven't done this.
If you have already done the aforementioned, then I'd have to be inclined to say it is the TMax unit itself and some just so happened to get a bad batch of TMax's if this situation is documented as "more than just a few".
I'm sure my suggestions are not "6th gear light indicator" specific, but you never know what does what and where with this hi-tech gadgetry. Uninstall and reinstall the Zippers TMax software, maybe there was a "bug" with the initial install. Update and proceed with reloading.
These are things I'd do and I'm sure you've done. After I'd done all this and it STILL didn't work properly, I, myself, would officially declare the TMax you have as defunct.....................unless I've missed something.
UltraKla$$ic , could you please send the reprogramming info to me at v4588@yahoo.com Thanks...

Ace, have you tried to do a reprogramming of the base map? I'm sure you have, but I'm just asking and the reason being, the first time I loaded my base map, I "thought" I had followed the instructions to the letter, however, my cruise light would stay on continually. Asked the gurus and they said ride it and over time is should "go away". I said screw that! I called Randy and he sent me CORRECT instructions on how to reprogram the TMax(more than just clearing IAC's), I followed these instructions to the letter, reloaded my base map as this step is incorporated in the reprogramming steps and all is fine now. All lights and indicators work as OEM.

What did he email you that's different than what is in the documentation?

If you have problems associated with your ThunderMax, there is a good possibility that the module firmware or a file(s) has become corrupt during the installation or tuning processes. The following procedures should be followed before the unit is sent back for testing. These processes will fully re-program the ThunderMax and clear any learned changes the system may have stored. You must have the latest firmware file on hand to do this, and should be running the latest version software. Updating the firmware and software requires an internet connection.
First, check to see that you are running the latest version of the software. From the toolbar, click [Configure] [SmartLink Update] [Check]. The system will inform you if a later version is available. If so, download and install the software update (follow on-screen prompts).
Second, to verify that you have the latest firmware stored within your SmartLink program for transfer to your ThunderMax, follow these steps: Click [Configure] on the toolbar, then [Firmware] [Check for Firmware Upgrade]. Highlight the Latest Version and click [OK] (firmware file is downloaded).
You are now ready to fully re-program your ThunderMax. You must be linked to the module to perform these steps. Close any open programs on your computer except SmartLink. If any of these processes are interrupted for any reason, start over at Step 1.
1. Clear the Diagnostic Trouble Codes. From the Tuning Tree, click [Module Configuration] [Diagnostic Codes] [Clear Diagnostic Codes].
2. Clear learned fuel and IAC adjustments. From the toolbar, click [Map Editing] [Clear âLearned Fuel Adjustments (CLP Offsetâ] [ Clear âLearned Idle Control Adjustments (IAC)â]
3. Reload the Module Firmware. From the toolbar, click [Configure] [Firmware] [ Upgrade Module Firmware Now] (follow prompts exactly).
4. Reload a best-match map. Update your module base maps library by clicking from the toolbar [EFI Maps] [EFI Map Listings / Definitions] [Update Definition File]. Follow steps 3-6 in the Installation / Setup Guide V2007.05.31 to load a new base map (available from http://www.thunder-max.com/Support/I...onManuals.aspx if you donât have your original version).
5. Confirm Module Settings of speedometer calibration ([Module Configuration] [Basic Settings] [Write Basic Settings] from the Tuning Tree) and AutoTune settings from the toolbar [Configure] [Closed Loop Module Settings]. Ensure that all four boxes are checked in the [Closed Loop Processing] and [AutoTune] commands (follow step 7 in the Installation / Setup Guide V2007.05.31).
6. Initialize the ThunderMax system and evaluate with a road test.
Generally, firmware or file glitches are caused by a sequence of events that can range from something as simple as a cross-keying the keyboard to installation of the components in in-correct order. Our experience has shown that the majority of issues can be solved by the above âclean sheetâ approach. If the above steps donât cure your issue, please contact us at ProductSupport@ZippersPerformance.com. Thanks for purchasing ThunderMax Products
Thanks for posting. So this didn't fix the issue for ya? As I stated, I'd be inclined to say you have a TMax hardware issue and even though it is relatively benign, an issue nonetheless.
