 |
|
I just got my edis advance table tuned a bit today. I'm curious what other people who've gotten their edis systems working are running.
And for those of you interested, here's a datalog.

That's pretty close to mine but you are a little more aggresive below 2000rpm than I am. I am going to wait till I get some sort of knock detection before I tune further. If you still interested I will try to post what I have.
I take it you have gone MS. Are you injected yet?

I'm definately interested in what your running. I havn't got injection going yet I wanted to get the EDIS going and tuned properly before doing fuel. And I still have to install the tps on my throttlebody, just have to finish the mounting bracket. I've been running EDIS only for a couple weeks now.

EDIS = Electronic Distributorless Ignition System. It means people running it don't have a distributor anymore, and they are able to map the ignition advance in a table like what I posted in my first post.

So, when do we get the how-to or at least some nice pictures to motivate other guys?

I suppose I could post some pictures of what I did. Didn't really think anyone would be interested honestly. I'll pull the car into the garage tonight and take some.

Here is an older map I have. I am boosted so it will be a little more compact than yours plus I am running MJLJ wich only supports 10x10 tables instead of the 12x12 that MSnS uses. I have actually pulled back some of my timing above 3000 rpm on my newest maps and have spread them out to 200kpa for anticipated boost at a later date. I fully realize these are quite conservitive numbers but I feel I can tweak these later if I feel I need more power or fuel milage.

I'm actually running a megasquirt II with v3.0 mainboard, which supports 12x12 for spark and fuel maps. The map I posted is pretty much a copy/paste from a excel spreadsheet someone posted on the megasquirt forum for determining a good 'starting' map. So its interesting to see what your running, did you notice any problems running 39 degree's advanced? I tried a map running 32 degree's advanced at 100kpa and slowly upped it to 34, I havn't tried anything higher than that yet. Was being cautious.

I run 35-40 kpa at cruise and only 85kpa key-on engine-off. I am at 3500feet elevation. Looking at my map again it looks a little screwy. I know before I boosted I was running 38° advance at 3000 rpm with no noticable problems even with the higher compression. I got a little scared though after seeing pictures of Nick's first engine. It looked like someone took a ballpeen hammer to the piston tops and he says he never heard the detonation! I did try once upping the timing at low rpm's and moderate loads (60kpa or so) to see if I could detect the ping and I couldn't. Let caution be your guide.

I'm running a megasquirt II, endwrench and macbdog are running megajolt. They both use map sensors to determine Kpa. We're running ford EDIS systems. www.megasquirt.info for more information on the megasquirt.

what are all the sensor you have and and to add?? cam position, crank poition, i know throttle and map is that it? are your injector firing per cyclender timing? |

Hmm, interesting. 2 dim. Ign maps., why no numbers after 6000 rpm todd?
min, very aggressive ign numbers , while cruising, idle etc.
