Is it doable, yes i believe so, i do have it running on the bench, but not tested yet in a vechicle. the down side so far is it will need a 24x ckp and possibly crank relearn. I'm working with a p01 8322 OS. So i actually ended up getting a logic analyzer and captured the spi bits being sent over to the CIC chip,
for 24x code they are 00 A7 00 20 30 0E 09 01 , These are loaded at adress 28434 for 24x. For 3x or 4x they are 00 80 80 A0 30 0E 09 01 ,these are loaded at 28420, sent via spi routine at 6E58C. What i ended up doing is to mod a 5.3 bin by changing #cly to 6 and A7 of the spi bits to 65.
A7 corresponds to bit 5 of the spi configuration bits on pg 65 of the CIC document i previously shareed on this site, bits 0,1,2 determine # of coils
bits 6,7 the calculated value of the lo res signal, bit 5 = hi res if set or lo res, bit 3&4 not used.
This is how it's wired on my bench simulator ign1=red26, ign2-not firing, ign3-not firing, ign4=red68, ign5=red28, ign6=red67, ign7=red27, ign8=red66
injectors 1=blu36, 2-not firing, 3-not firing, 4=blu76, 5=blu57, 6=blu4, 7=b43, 8=blu77
Hope this helps, but like i said havn't run it on an engine yet.

What are you using for a bench simulator

Re: Coil over plug 6cyl
I tried to play on the bench but my 24x simulator (arduino) failed to make it right and I had a code about CKP sensor malfunction
I also interested to make 6x coils cuz I hate limitations with one
I cant retard ignition significantly cuz spark will jump next cyl

I ended up getting an ardustim, you can find them online

Re: Coil over plug 6cyl
ardustim is adruino nano based simulator. i have a post here concerning ardustim, ended up finding the wheel def for ls24x from git hub was inverted after correcting it i was able to get an rpm reading on logger. i believe i was also getting sensor malf code until i fixed wheel def, hope this helps.

Re: Coil over plug 6cyl
Is there any chance that this could work with a 3x setup?

Looks like no one succeeded or not willing to share experience )
