has anyone installed the mega squirt system on there 240
Well I'm getting ready to install the mega squirt stand alone system on my 240 but. I'm not to sure if I can run my distrubter or if i have to go to a dis system. does the ka24e have a ignation madule or the ka24de cuz i'm doing the e to de head swap as well and need to know if i can run the distrubter with this system or do i have to do the dis conversion to it. Any info will help.

A couple people have done it to 240 and similar, but they probably wont post here. I am in the installation phase myself. Ok so you want to run megasquirt with spark control?, or let the stock ecu take care of timing and use mega only for fuel control?(not sure if this can be done with decent timing maps). If you prefer the latter, you will need to piggyback various ecu input/output (tps, rpm, possibly o2?). Im not at all sure if this is possible, i looked into it a while back, and tps is obvious problem as well as the the others that require source voltage.
If you want to run megasquirt&spark (which is full fuel and timing control) you will need to modify your distributor/cas to a flying magnet type pickup system. Either do it this way, or go to a full distributorless ignition system. This requires a 36 tooth -1 to be fitted to the crank damper, a vr sensor, and you have a few aftermarket options as far as coil, and dis unit. I am using the motorcraft edis4 system which requires the above components, this can be used with megasquirt for full standalone fuel/timing maps, pw, ds, dwell etc etc.... total control of all parameters and decent tables. This type of setup is commonly known as megasquirt&edis. Requires small modification of Fidle signal on megasquirt ecu, pip and saw signals, and software to tune.
If you are doing the sohc/dohc head swap with rwd head, you can use either distributor. Possibly with stock ecu control and mega for fuel, or modified via magnets for timing control with mega, or dis, few other options as well such as HEI. Just read all the info you can find on the megasquirt boards, easy to learn.
