boldy205 74 Posted November 7, 2022 Hi all. I've currently got my 205 with a Rotrex charged Gti6 engine in for a stand alone ECU and wiring harness. The chap who is making the harness is trying to find a base map. Anyone know of anything I might be able to use? I appreciate I may need to pay etc, just looking to see what's available. Thanks!!

petert 549 Posted November 7, 2022 (edited) I might be able to help. You didn't say what ecu. I have one for a Haltech E6X. It's in msec rather than VE, so you'd need to export the maps and transcribe the numbers. At least you'd get the shape correct. The ignition is map is very safe.

boldy205 74 Posted November 7, 2022 (edited) Hi Peter. It's an ECU Masters Black. Just need something to run the car to check that the new look is all functioning as it should. Then obviously get it all set up on the rollers What's the difference between msec and VE? Thanks Matt Edited November 7, 2022 by boldy205 Additional info Share this post Link to post Share on other sites
petert 549 Posted November 8, 2022 Milliseconds is just the raw amount of fuel delivered. Volumetric efficiency is a measurement of how much air is actually going into the engine. Most new ecu's are VE now. https://www.haltech.com/news-events/tuning-with-ve-volumetric-efficiency/ Share this post Link to post Share on other sites
boldy205 74 Posted November 8, 2022 Thanks for the link, helped explain things well. The chap who is doing the loom has contacted ECU Masters, apparently they may well have a map, however the chap who can sort it is currently on holiday! Typical! Fingers crossed he's back soon Share this post Link to post Share on other sites
welshpug 1,619 Posted November 8, 2022 (edited) Is there not an actuator test function? With my DTA there's a coil driver and ignition driver test function, sets them pulsing for a given period of time. You dont need a map loaded to do this, Edited November 8, 2022 by welshpug Share this post Link to post Share on other sites
boldy205 74 Posted November 8, 2022 Yes, I'm sure there is. Just that the car had had a fair bit of electrical work done on it to fit the new ECU. Due to this both myself and the guy doing the work would rather we could see it running prior to the RR session. I've been in contact with ECU Masters and have finally found someone there who looks like he can help. Share this post Link to post Share on other sites
Spesh 28 1 Cars Posted November 10, 2022 https://tunes.speeduino.com/#/t/LHFK1zvftX/tune/settings/engine_constants Thats the tune thats on mine albeit alphaN on ITBS. Share this post Link to post Share on other sites
petert 549 Posted November 10, 2022 Do you think it's better or worse to be on alphaN compared to straight MAP for a supercharged engine? Share this post Link to post Share on other sites
boldy205 74 Posted November 18, 2022 Hi Guys. Just a thought, does anyone have a map for a standard Gti6 engine? This would do to get it running. It would need to be for sequential ignition and fueling. I understand a lot of people convert to wasted spark, and therefore non sequential ignition when fitting aftermarket ECUs.
