You may find that you need to redo mixture also . Point is to get as high revs as possible with advance for same throttle opening , but without pinking or running rought . You can do that for idle and whole reving range in neutral . After that , back few degries through Kpa , something like -6 degri...

I was talking about anti-theft protection. Connect coil + to secret switch , not MJL . Car can be stolen , even if you take out MJL . Ignition can operate on edis , and egine would run , so it could be stolen .

Hi Dominik ,
I think it's better to use hidden switch for coil + , or ground via switch one wire from CP sensor .
Ignition can work on EDIS without MJL

I forgot to say , that I am using 0.7 gap on sparks.

This is a map from my 2.0 pinto powered s7 . Ported head , DGAV carb , 4-1 manifold ...
Works nice .

Thanks Brent

I was investing some data about 68HC908KX8CPE , to find power usage . I found that processor is 8 MHz , and my oscilator is 16Mhz . Is it ok ?

I did that , and I saw 40mA , with and without resistor . I measured 180 Ohm on board power supply to processor ( gnd and 5v ) , and 28 Ohm on same processor pins ( 1 & 16). I dont know much about electronic , but my verdict is that processor has gone . I am in doubt ; how this has happen ? I sw...

And update :
I checked current draw with microcontroler out , it's 40mA . When i put microcontorler on current draw was 400 mA . So its microcontroler , or oscillator . I think its first one
What are my options for repaire ?

Hi Brent I repalced max 232 , and put socket first :) . Tried controler on car , but I didnt see spark advance . Curent draw was 400mA :shock: . LED controled by user outputs were doing some crazy stuff . Without + to controler , all LEDs are ON , and when I connect + ( turn on controler ) , just on...

Thanks Brent for fast answer . 200 mA is draw from 9v battery to board without microcontroler and ULN . Molex was disconnected , only + and - pins were feed from battery . I replaced all power componenst ( voltage regulator , C1,C2 , D2,D3,D4,D5 ) .Didnt touch anything else , just resolder joints . ...

Hi Brent . I saw 200 mA without microcontroler and ULN . Voltage regulator is getting warm , but not to hot for my finger . I dont know , but I think 50 C or somethig like that . As I said , everything was normal , and one day I started engine , a MJL didnt wont to work . I wont to put pad ( i dont ...

Hi Brent Nice to see you here 8) I did that , when controler was new . I tested connection with 9v battery. And evry thing was fine . Now , after a problem , i fixed voltage regulator , MJL doesnt communicat with PC , not on car 12v. Battery cant even deliver 5v to microcontroler . User outputs are ...

For a weekend I went to garage ,and plug MJL to car instalation . I started the engine but controler wasnt advacing ignition timing . It recives solid Vout 5v , and my user output LED , programed to switch on 4k , 5k and 6k rpm , are liting constantly. So ULN is working somethig , and probably micro...

Thanks Ryan Odd thing is happening . I bought new voltage regulator and I soldered V in pin and Gnd pin first , connect new 9v battery . I saw 9v in pins , and 5 v on Vout . I soldered Vout pin to board . I check again , and voltage was 6v on Vin and Gnd . 3.9v between Gnd and Vout . I didnt try wit...
