ECMLink (V3Lite) Firmware Changelog
3.26.72 (10/09/2013)
Added “cranking fuel cut” feature to EVO1-3 chips (was already in other versions). When cranking the engine with the throttle to the floor, ECMLink cuts fuel to provide a way of clearing out a flooded engine. The ECU does need to “see” a low throttle angle some time before cranking or else it will flag the TPS as bad and then disable the cranking fuel cut feature. So floor the throttle only when you're just about to start cranking.
Reduced the minimum injector pulsewidth in order to support larger injectors at idle.
Changed cranking fuel cut not to activate the cut unless less than WOT is seen as some point after ECU power-up. This prevents a bad TPS signal from inadvertently triggering cranking fuel cut.
3.24.152 (04/25/2012)
3.24.143 (04/24/2012)
3.20.115 (03/22/2010)
3.20.107 (03/16/2010)
Extended V3Lite functionality to include RPM-based fuel and timing tabs as well as the MAFComp tab required to use our automated
MAF adjustment tool.
3.20.52 (01/25/2010)
3.19.139 (12/23/2009)
Enhanced logging of various bit values (ECU pin inputs, etc.) to increase logging rate when viewing those items.
Changed logging of LoadFactor to increase log rate.
Released a new and improved AFRatioEst that makes using this critical log item even easier and more accurate, particularly with larger injectors at idle and even cruise conditions.
Adjusted MAF edge detection logic to be more accurate.
3.19.49 (09/17/2009)
Added support for extended timing and fuel tables. This increases both the size and resolution of the open loop fuel table and also increases the usable resolution on the timing table.
Adjusted the stock TmngMaxOct and TmngMinOct tables a bit to remove some of the goofiness defined by the factory on the highest load row.
To use this release, you MUST download and install at least version 3.19.49 of the
laptop application first.
3.19.40 (09/08/2009)
Original release. Supports EVO1-3 ECUs. Some details
here.
