TephraXMOD V2 has been superceeded by TephraXMOD V3.
KnockCEL - A beloved feature from TephraMOD on CT9A, of course makes a comeback in V2 - different flashing rates for “low” and “high” knock thresholds
Knock TPSCUT - Pretty much an extension of KnockCEL, this allows the ECU to cut the throttle to a configurable value in the event of a knock threshold being reached - This is literally a motor saver - and can easily be disabled by setting the TPS CUT value to 100%
Alt Map - Allows for configuring upto 8 alternate map sets. This means you can have a pump tune, E85 tune, E100 tune, valet setup, or pretty much any other combination of setup you like. The map-set covers the main maps (fuel/timing/boost,rev limits).
Note - It is important to realise that altmaps and Flex Fuel are mutually exclusive, meaning you cant run both at the same time.
No Lift to Shift - Drag race much? NLTS should give you a tenth or two. By keeping the throttle flat during changes you reduce turbo lag, and thus get almost instant power when you release the clutch.
Note - That NLTS isn’t for the weak knee’d, it also involves imposing temporary fuel cuts which may or may not be bad for shock sensitive components of your engine! To date I have yet to hear of a failure caused by NLTS
High/Low Gear MIVEC - Lets you treat MIVEC like the Boost Crossover, meaning you can have a different MIVEC setup for first/second/third from fourth and fifth, or whatever crossover you like.
Live Tuning - Sick of stoping/flashing/starting? Wouldn’t it be easier to live tune??
MethSafe - Perhaps inappropriately named, but Methsafe allows you to hook up an external controller, whether it be meth or NOS controller or something else to demand the ECU swap maps.
Currently there are two activation methods:
5V ADC map switching:
You can connect your meth/nos controller to the ECU (using pin 112) it must output 0v on FAILURE, and 5v on SYSTEM OK
Because USDM have EVAP USDM vehicles cannot use this method - please use Resistor ADC instead
When the ECU sees the voltage go ABOVE the threshold it will start the timer to swap to MethSafe maps.
When the ECU sees the voltage go BELOW the threshold it will INSTANTLY swap to normal maps.
Resistor ADC map switching:
You can connect your meth/nos controller to the ECU (using pin 115) it must use a relay to ground pin 115. It is preferable to use a ~250Ohm resistor between pin115 and ground
When the ECU sees the voltage go ABOVE the threshold it will INSTANTLY swap to normal maps.
When the ECU sees the voltage go BELOW the threshold it will start the timer to swap to MethSafe maps.

TephraXMOD V2 was $50 (USD), if you wish to upgrade to V3 its only $50 (USD) as opposed to a new VIN cost of $100 (USD)
Refunds due to incorrect ROM selection will be minus the PayPal fees (Blame PayPal for changing their policy on fee refunds in 2019)
In order to flash V2 OR V3 normally (ie in Car, and not on a Bench), you must be using EcuFlash 1.44.4xxx and above; additionally you need to configure your EcuFlash to ignore the “protected memory areas”, by downloading and running the mitsucan_memory_override registry file. Simply open the zip, and double click the reg file inside, you will be warned when running the reg file, but be assured it’s perfectly safe! :)
