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.
Reduce the minimum injector pulsewidth in order to support larger injectors at idle.
Fixed bug in cranking fuel cut that required cranking for a period of time without the throttle to the floor first before pressing the throttle down to activate the cut. Now the check for low throttle angle takes place whether you're cranking or not. And once flagged good it remains good until the next ECU restart.
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.
