Autronic and injectors
Hi,
I am putting a series 5 13BT in my 1980 RX-7. I will be using Autronic SM2 ECU with 1.49 Rotary chip. What kind of injectors, and how big should I go for? Any cheap online shops?
Can I still use the 550's for primary and go for 1600's for the secondarys? I think I read somewhere that the Autronic liked the injectors to be the same.
Regards,
Frode

you must run the same injectors. apparently the autronic can control large injectors very well, so you can get away with 4 1600cc inj if you wish. i am running 4 rochestor 1000cc inj with my sm2.
have you got it running yet? if you need help let us know.

Yes use four of the same injectors. The autronic will idle anything, their injector drivers are amazing!!
Im currently using an SM2 1.49 as well. If you need any help getting it running let me know.

Thanks. I will get four injectors then. Any online shops that sells injectors that suits the autronic? I would prefer something that fitted right away in the intermediate housing and lower intake manifold. The base on the original 550's is 16mm, and my local dealer only had injectors that were 14mm, quite expensive too.
Will I have to modifiy the original trigger setup, or will I get away with only using the reluctor adapter?
What is you guys actually running? for ignition and fuel delivery?

i think enzo is using the bosch 1600cc inj. these are cheaper, but i'm not sure how they fit.

ORX795, Thanks! That helps a lot
Engine is Series 5 13BT, streetported, with portmatched intake and throttlebody-mod. I will be boosting about 16-17 psi with 60-1 turbo. Was thinking about going the full route with R500 4ch CDI, is it worth it?

Im currently using the 500R CDI with 4 MSD Blaster coils. Spark is plenty powerful!!! Is it worth it, ABSOLUTELY! Im thinking of using different coils though, maybe Crane PS92
Use the stock CAS and set your mode flags as ORX705 stated.

would it be worth putting the 500r on my car? it's putting out only 320hp on a dynodynamics.

It was for me because i didn't already own any cdi boxes(msd, crane, etc). So for me buying the 500R would cost me slightly more then 3 MSD units or whatever else i would get.
Plus the Spark output is greater, It doesn't take up nearly as much room as 3 seperate cdi's would, and wiring is neater.
So i would say if you already have something hooked up and running fine leave it until something goes wrong with it or until it doesn't support your power levels.
Then its time to yank it out and put in a 500R!!!

enzo: So there's no problems with the unit getting too hot, that is cool I have none of the FC ignition stuff, so I think I will get the 500R unit. Crane coils are the way to go?
Thanks,

I am running the R500, one dual-post and two single-pot M&W coils. I have it hot-rodded in high power mode all the time.
For fuel I am running 1600cc all the way around, Toyota Supra fuel pump, and a SX-Engineering adjustable fuel pressure regulator.
As Enzo stated, mode flag 13 to 2, 14 to 6 and 15 to 1 and your car will run. make sure you wire all eight injecotor outputs exactly as Autronic shows and set it up for 4 cylinder 4 stroke.
