As i said in other post, recently i own MSII fuel and spark control, it's working on the simulator, and i need a base map for it.
Anyone here willing to give some help to minimize the effort?
I allready pm to terrastudios but no answer.

I've planned to connect msII directly to the original 480 connector loom, disconnecting the fuel and ignition ecu's and wiring the ms2 to it, in order to benefit from the original relays and fuses.

Thank in advance.

Hey

Sorry for not replying sooner, what engine you using?

Plenty of fuel and ignition maps about for 8v fords ( 1.8 ) - base your setup around this

I'm not running a Volvo engine, I'm running a modified F7P (Renault 19) engine so my settings won't be much use to you, as it has a different flywheel arrangement, fueling and ignition requirements.

You'll need to drive a standard ignition coil if you have the ignition module as the Megasquirt can not drive the Renault/Volvo ignition coil. I currently have a standard +12v coil wired in an a VB921 FET driver which GNDs the coil on an ignition event.

Speak soon

Matt.

thank you terrastudios

i'll search for ford 1.8 maps.

The engine is 18bft, standard untill i'll make it run.
I heard some about not working to controll the original ignition module on volvo, and i plan to controll coil directly.
My MS2 have a driver for coil(vb921).
Any ideea to controll the boost actuator?
Thank you again.

I can't help too much with fuel maps, since the standard syatem is mas flow, and yours is speed density. Ignition timing, maybe I can sort out something.

The boost solonoid is easy to operate. It's just a pulse width modulated valve. It's designed to operate at 120hz and is set up so that at 0 duty all the air goes to the turbo actuator, at 100% duty no air goes to the actuator. You will want to be sticking to 20% to 85% duty though as outside of that it won't do much of anything usefull.

To control it a PID loop, acting against a preset boost setpoint (or indeed a map of boost setpoints) should work well enough. I'm guessing that MS can do that sort of thing.

Hope that helps

Richard

I'm planning on firing up my eprom reader and hunting out the Maps on the siemens F7P ecu, I've also got a siemens B20F ecu in bits on my desk as well so if I get chance I'll attempt to hunt out the VE and Adv tables on this one also. If I find anything of use I'll post it up here (unless I get shot down by Siemens! in the meantime - not sure legally how I stand on such matters).

My only fear is they've used some weird scaling thats going to take me ages to work out, I've got a very short attention span!

rpruen · Post by **rpruen** » Wed Dec 20, 2006 12:09 am

I don't see any reason not to post it here. Legaly it's not your info to post. I guess that the site admin could be asked to take it down at worst?

I have an agreement not to post info about the ECUs for the turbo, so I will have to stick to that. You don't have anything of that sort, so I guess it's up to you.

As for figuring out what is going on... It shouldn't be that bad. I think that some of the tuning software (EVC etc) understands the maps in the ES ecu, as to them telling you the scale etc... I don't know I have not tried.

Well, heres the SparkAdvance map for an F7P (16v 1.8 ), hope this is of some use to you! All numbers in the table are obviously in degrees.

Load is specified in kPA.

Hi all,

Been busy with my chip reader and found the below ignition settings for a b18ft engine - be a good start for Megasquirt users etc..

Have a good Christmas!

That's great info.
I will try to make a nice graphs in Excel of them.
Now just find the rev limiter in the EZK and raised from +/-6200rpm to 6500rpm.

What program did you used to read the eprom? Could you post or send the whole file extracted from the eprom? (Renix or EZK)

terrastudios · Post by **terrastudios** » Wed Dec 27, 2006 4:51 pm

Hi!

I'm not sure about sharing the ignition and fuel EPROM dumps, sorry! I don't think its strictly legal - however you can get eprom readers easily enough which come with software. Once you've read the IC its just a matter of hunting out the data.

Speak soon

Matt

only good news here.... and i like it

keep on

p.s. ...10x16 ignition map on ezk?

Ettore Bugatti · Post by **Ettore Bugatti** » Wed Dec 27, 2006 10:18 pm

No problem, I can understand your reserverations about it. Altough I see them as sharing jet settings on a carb.

But why do you use Megasquirt when you can change the original ECU?

Is the data from B18FT pre 91 or after?

What Eprom burner/reader would you recommend?

Anyway here are some graphs of the posted data.

if the question was for me, megasquirt is designated for the "fun car", the third one, a future drag car.

for my car i will stay on original ecu's

terrastudios · Post by **terrastudios** » Thu Dec 28, 2006 8:16 am

Thanks for graphing the data, I did have a go at doing that myself but I had a mental block and could not figure out how to do it in Excel!

Reason I am using Megasquirt is I'm running a F7P (16v Renault 19) engine in my 440, the F7P has been bored out and is running custom cams. Although it is possible to use the original Renault engine management (I did this at first), the Megasquirt is a lot more flexible. Granted its taking a lot longer to get the car running exactly how I like, but it means in the next few months, if, I decide to turbo conversion the engine I can leave all the electronics the same in the car, as the Megasquirt works up to 20psi of boost!

It is also a great learning tool, the more I play and tune up the 440 the more I learn about electronic fuel injection cars, and really thats what the whole project has been about - my Dad passing on his mechanical knowledge of engines to me, and me learning about EFI technology. I'm one of these people that has to do something to learn, I struggle reading literature to educate myself!

Speak to you soon,
Thanks again,

Matt.

I think the data from the B18FT EZK needs to be adjusted slightly. The map doesn't look right, usually at high revs and high boost it would be retarding the ignition. My guess is the data in the map is something along the lines of number of teeth after 90BTDC (remembering the MS2 trigger and trigger return points etc)

terrastudios · Post by **terrastudios** » Thu Dec 28, 2006 11:42 am

I guess the way the ECU works is it uses the above map as a base (much like Megasquirt) and then applies corrections to these values at real time - possibly with another table which references boost values, but it should give you a bit of a starting point.

hjkort · Post by **hjkort** » Tue Jan 02, 2007 9:47 am

just insert the numbers in Excel and select the surface graph, et presto...

Information added on my site

terrastudios · Post by **terrastudios** » Tue Jan 02, 2007 12:38 pm

Hey

Thanks for the excel tip - graphed all my tables now (fuel + ve) for the F7P - looks amazing

Looking at the above graph for the B18FT i've just noticed the load scale is the wrong way round, which is why the graph is back to front!
