EFI base maps

[Mr Locust]

I'm currently starting an upgrade to my Lumenition ignition/injection ECU due to not being able to access the mapping (even Lumenition can't access it as it requires a 1993 vintage Psion computer).

Based on previous good experience with other cars, Emerald K6 ECU is the way forwards; just in case I have to start from scratch, does anyone have any base fuel/ignition maps which could be used as a start point for a 912HC engine on 104/107 cams. Preferably Emerald but I can transcribe or cut/paste maps from other controller types if required.

Thanks in advance.

I'm sure Jerry will be along soon!!

I'd be happy to share my maps - it's a DTA system with fuel injection on a 912HC. Not sure how useful they would be as the throttle position is not directly translateable (I have 48mm twin Jenvey TBs) and of course the injector specification will affect the amount of fuel delivered - the map shows open time in ms.

However it's a start!

Thanks for the offer Richard. I'll e-mail via the forum, hopefully that allows you attach the file by return.

I downloaded the DTA software and it looks like it should be reasonably easy to generate an Emerald equivalent as Emerald software allows configuration of TPS% and RPM sites to make the same table row and column headers.

Emerald have now said they can generate a map from the original controller by logging a bench test simulation so it will interesting to make a comparison of my original map and yours in the same format as I know the areas of the maps on my engine which need work.

Hi guys I am soon to go through this aswell, I am starting by ignition only and then EFI, would either of you guys be willing to share the ignition maps to give me a starting point?

My car is running the emerald3d with 48mm tbs, as my car is having a LSD fitted at the moment I can't access it until next weekend at the earliest. Not sure if my map will be of help as my engines is no where near standard. She runs over 250hp with big injectors but you are welcome to a copy.

I will check my laptop to see if I have an earlier map which I could send you over this weekend.

Hi Paul do you have the DTA software? If so I'll send you a copy of mu map.

Hi no I am not using a dta system just need a reasonable base map to start from. I maybe able to download it thou do would be grateful if you could

[Mr Locust]

Thanks Jerry. It will be an interesting exercise to compare a few maps while I'm waiting for my ECU to arrive....

I'm currently pulling Richard's map into the Emerald software to make comparisons possible in a common format.
