Base map wanted Lotus 912

Post by annteak »

Hi I have the S40Pro ECU and its all new to me !

I believe its a 36 pin wheel (it has 35 teeth and one missing)

TDC is marked 4 teeth away from the missing tooth, so do I set it as 4 teeth to TDC or 5 Teeth (to account for the missing tooth)?

Otherwise once I have that set up I think I should be good to start it, but I have no map so can anyone offer one?

Have a look in the manual; there's a useful picture showing trigger wheel and how to work out where the sensor is in relation to TDC.

The zetec map will most likely get you running once you have set up the crank sensor position.

I think you best get a copy of the DTA manual - and read it, and then read it again! The Zetec 2.0L map file will be about as close to a 'universal' starter map as you are likely to get - it won't be correct but once you understand what all the 'bells & whistles' in the software do you can adjust it more to suit what you are trying to run, then say it as say, 912.map then you can revise it and save it to your heart's content.

Annteak, I have a Lotus 912 with DTA S40. You are welcome to have my map. Without knowing more about your engine, it's difficult to know how good mine would be; I recently spoke with someone with a S2 Esprit with a 912 engine and we concluded he'd be better off going to a rolling road. Things like throttle body and injector sizes may well differ.

As others on here have advised me in the past, as a minimum you should fit a wideband lambda if you are going to do any tuning yourself.

Hi Richard,

its booked into Northampton Motorsport who are going to do the rolling road tuning / mapping session end of November, (so lambda passion fitted to exhaust and they use there sensors), but in the mean time I wanted to get it started so I can check for leaks etc... also move the car around a bit to check clutch gears axles etc. Nothing worse than going 50 miles on a trailer to a tune session and the clutch slips or the engine has a leak etc!

So a copy of you Map would be welcome to get me started if nothing else :)

Not sure what I can tell you about it other than its now in the front of a Vauxhall Viva GT, all very tight down the bottom for things like crank sensors.

here is the engine in the car

And here is the car itself, as of May 2019, nothing changed since then other than loads of little jobs to get me to the stage where I need to think about Maps.
