this works very well in MSII 0-5v

Hi all

I used this circuit to my MSII, it´s works for MJLJ v4?

change the max232, this is the problem

I have a 1.03 and 1.04 "High performance, low cost aftermarket automotive electronics."

I sent you the e-mail by MP

the tracks were not burned, are good. now remove the connectors ;) As I say, here in Chile there is no "FDS6681Z P-Channel MOSFET and PNP transistor SMBT2907A" which serves as a replacement for another me http://i317.photobucket.com/albums/mm399/Fabian1380/Dibujorev.jpg yesterday afternoon...

Salamander, If the ground connection going to the rev limiter does not make good contact then this will very quickly damage the Mosfet. This might have happened in your case. The Mosfet specified in the Rev Limiter has plenty of current carrying capacity for EDIS-4 operation, so this should not nor...

A4T ahead of me because the ignition failed. t º is cold, no problems. on the cables, they are loose because yesterday when he missed the U1, I have to splice to return home. very rare find everything, as I told them, I have several years walking with the V3 and never a problem, now I come all, I do...

Hello everyone after 2 years of using my MJLJ, never had a problem. now paint my car after I have many problems. what the fuck is wrong! the last week a have problem with the MAX232 http://www.autosportlabs.org/viewtopic.php?t=2524 RPM's and no advance time, there were only connection to the laptop ...

yes, works 100% thanks Brent

thanks brent for your time. I folow the lines of the circuit and all is correct ( http://www.autosportlabs.net/asl_dist/mjlj/mjlj_v3_sch.png ), I connect again the MJLJ and all works, the problem is the 232, I dont' know what is the problem in my mjlj, is posible a high voltage burn the 232? my shif...

Now I change the 232, the line pip1 is 12v and 6.5 running
but, no conection laptop

OK, I change the 232 tomorow

look this,
the v4 works with 12v-gnd-pip and saw, all good.
the v3 I connect the same wires and no signal to PC, only tps

I make a test of 5v and 12v in the circuit, all fine.

when I connect de V3 the volts in PIP3 falls to 1.15v I disconnect the V3 te pip vols is 12 or more.

I dont' know, V3 not read RPMs and advance, and V4 read MAP but don't start and de PIP3 is 12v
