CVT Torque Protection Override Z27A Colt Ralliart

Colt Ralliart CVT

Another quick post – this time on how to disable the Mitsubishi Colt Ralliart CVT torque limiting behavior holding back your fun.  Not sure if you’re hitting the CVT torque protection? Log your throttle and if it’s never hitting low numbers in the 16-20 range, then chances are you’re in a limp mode. ECU has a half throttle limp mode, and then a 1/4 throttle limp mode when its really upset.  Warning – these torque limits are there for a reason – to protect your CVT from damage.   If removing them, consider trans cooler and more regular gearbox fluid changes to try and minimise the extra risk you’re taking on.


For ECU ID 39780007

Add the following to your XML:


<table name="CVT TorqueLimitByPass1 Set All to FF" category="Limits" address="ab1e" type="2D" level="1" scaling="Hex8">
<table name="X" address="b23a" type="X Axis" elements="11" scaling="RPM"/>

<table name="CVT TorqueLimitBypass2 Set Inc 102->0" category="Limits" address="2368" type="2D" level="1" scaling="uint16">
<table name="X" address="b11e" type="Static X Axis" elements="1" scaling="RPM"/>


Then for the first map set all to FF, 2nd Map set to zero.  I think from memory you only need to do one of these two.  If adventurous set one and test (and let me know), or just set both.
