CDI Systems with Water Injection
 

Hey guys,

ive got a 12a half bridge T04R Microtech LT10s with the X4 box..

Im looking for a CDI system that i can run on this with a rice racing water injection kit.. I also have a 13bt auto in a early mazda which i would want to use it on when i relocate back to australia from London, UK..

Ive got a mate whos coming to the USA next week so looking at something from JEGS or Summit..

Is there in the Crane or MSD range that may work.. I dont mind if its Leading only CDI or Both...
I want some guidance as ive not used or bought a CDI system before.

Cheers

I use dual crane fireball hi-6 ignition boxes for leading and 4 crane lx-92 coils. It sucks crane is out of business now, maybe you might want to get msd because of that, I'm not sure. Anyways I use this stuff along with the same ecu setup you have and it works well.

DOnt touch either brands with a 10 foot pole. I TOLD YOU to use the DYNATEK UNIT.

dont waste your time with anything else.

Only other brand i would use is the crane units.


I have tested the dynatek units to 9.2:1 fuel mixtures with 650cc of water 25psi of boost and no missfire and only missing around 35hp.

what did you guys run on thelevmans S3 rx7?? Dynatek?

In your experince omar whats the best you think long term for my use and then the 1300 when im back.

Crane or Dynatek?

my system,, 2 Crane HI6-2 boxes, and 4 Crane LX92 coils, plus a big CDI capacitor, to drive the box cdis.

complete setup was designed and installed at the Crane factory 5yrs ago, in daytona Fl,its a shame they went out of business.
i hope i wont need parts, because thet gettin hard to find NEW, used stuff could be questionable( like burned out)

pic of crane setup, iv had no breakup down to afr 9.9-10.
Crane hi6+2 box has 2 cdi in each box, so i have 4 actual cdis, and 4 coils, 10mm wires.
and a Microtech LTX8

Yes thelevman using dynatek.

and do you need to run their leads or can i still stick with my 8mm magnecor leads?

You can run any leads you want.

We are using basic 5 dollar each top gun leads on my 700rwhp rx7.

did you use the coils from dynatek or a different brand, im looking at all there coils on there website and not sure which is best to choose for 30psi of boost, 900cc of water

M&W CDI?

thewird

yeh speaking with the guys at dynatek they said that the HEC Bosch coils with the usual microtech install would be ok.. But they also do offer their own coils..

I think for now ill see how it goes with the coils i got.. I think ill need your assistance omar on the install too if thats cool. Will chat over msn or something.

Damon just get their coils.
The whole kit is cheap as.

You want the single .5 ohm coils.
If you pm me ill do you a good deal. bosch coils are shit house.

yeh nar i got the lot.. The place i got them from just waiting for the coils to come in so they will be sent seperate, a mates getting the unit as his in LA for work this week. :nod::nod:

how come with this forum also in the Auxiliary Injection topic there is like 472 topics but i can only see the front page..

You need to change the display options at the bottom of the page.

I've been using the Autronic 500R. The M&W apparently is the same but half the size. I have had success with it and a noticable improvement over stock. I fire about 400cc's of -40 windsheild washer fluid and it can fire rich mixtures without issue.

Have not really seen anyone run any other ignition setups around here other then thewird once he installs his M&W. Local FD race car that we pit for has put in the M&W but we are running race gas and 18psi. No aux injection. Tuned by CHAG auto in montreal.

I have just installed the accel 300 digital cdi unit on my leading coil and man better than the that huge msd unit I had in there. It's actually the size of the microtech lt10 or maybe smaller. Sucker really sparks hot. Noticeable difference especially on boost after 5000 rpm compared to the msd unit. This on the same tune. The car really needs to be tuned though

So ive installed the ARC2 and CDI and after an hr of driving i could hear the ARC2 box ticking..
I turned the car off and then restarted it and it went away but again 40min later it started doing the same..

Any one have this issue ??

can you take some pics of your installation, where you have connected everything up to where its placed in the engine bay.

Should give us some ideas abotu potential issues and for anyone who is gonna install that kit

Its a box with wires coming out of it with 12v ign and 12v constant and a earth

nothing more to it and its not in the engine bay

SO DOES THE CAR STOP RUNNING? Were is your earth going?

Car does run but havent had it out in a week..

Will be heading out in it tonight so will drop you a line on msn if your on your morning

yeh took the car out for cruise again and the arc2 is buzzin its head off.

just got off the phone from the tech guys in the USA and he said the only 2 reasons it would make the zap or ticking sound is if the main loom plug wasnt on properly which it is OR their is some solder issue inside and its arcing..

Going to send it to my mate whos running on here in the UK and get him to run it on his car..

here is a vid i took from my iphone - the sounds can be heard from about 7sec or so..
