well looking to get any info on how reliable the cdi box are
looking to use it with cbr coils.

 

Extremely reliable. I have tuned n/a cars over 400whp and turbo cars over 900whp with the CDI, with much success. It is my ignition of choice on all of my vehicles as well. Works flawlessly with wth CBR and AEM pencil coils.

 

The CDI is by far the worst product made by AEM. We destoyed 5 of them in a span of 20 minutes on our Supra. I would definately look elsewhere for a good CDI, I recommend M&W.

 

according to this thread its the best and the worst cdi available LOL


i would look into a M&W pro 14 if your looking into a COP set up.

ROFL -- this just in -- AEM CDI the Best and the Worst -- gotta love the internet

i have heard nothing but great things about the M&W

we are running an Autronic CDI that I bought in 2005 and haven't had an issue at all with it since - i believe the Autronic, M&W and Motec CDI are all very similar in performance, correct me if I am wrong

Yes there all very good.. The EFI Tech CDI is also a pretty good unit...

 

this things are nothing but junk we had nothing but issues with that box
i would try like an M&W box or a crane cams digital box they work great

 

Our AEM CDI box lasted 12 minutes before it went. car was idling good, shut it off, and it wouldn't turn back on. we actually spoke to a rep from AEM that we knew, and he even recommended going with at least the MSD box over the AEM, but strongly recommended the M&W pro-14. 2 years later and not one issue with it now. i seriously would not waste your money on the AEM box.

 

im sure its one of those issues where everybody is installing it wrong lol

 

Have the aem cdi in my car now running full sequential ignition and had no problems. Ran the old one for 2 years.. they are not the best but it works for me.

Thanks Enzo!

Unless the box has undergone a drastic design revision I wouldn't run it.

There are a huge variety of options in the CDI area.

M & W
Motec
EFI Technology Inc.
Autronic


We have had great success with ours, hell we used to run them in IRL 800+HP @ 13,000 RPM sustained for hours on end

 

I cant speak for the AEM CDI specifically, however we have been running the AEM Twin Fire with MSD Blaster SS coils on Van Nattens car for over a year now.

Seriously I lost track of how many boxes we have had to send back, but I would "guess" it to be in the 6-10 range.

I can say however that through actually working with AEM on the problem we think we figured it out. I'm no electrical guru, but the problem had something to do with the combination of the small sea-doo style battery we wear running and cold starts on cold days. something about the amps going through the roof and frying the box or something. Since then we have replaced the dry-cell with a optima red top and avoided cold starts on cold days. No problems since (just a 30lb heavier, heavy car!)

I know there was a major revision change to the Twin Fires early this year that was supposed to fix some major problems with the box.

I'm not going to knock the box, it's always performed great when it performed. And again I believe we fixed the problem that was more so on our end then the product end, but I wouldn't be surprised if others had the same problem and knocked it up to be the box, and or had one of the older boxes.

Just trying to give a little more then a "yes it sucks" or "yes it's great" response.

 

Haha, simple as that. No cold starts on cold days!

I've used the EFI Tech CDI in a 1650+hp Boat which had a water issue and the cdi was completely under water. I took it apart dried it out and put it back together and went 180+ mph. So i'd say there pretty reliable...

I've had car completely burn to the ground and if you would've looked at the car you would say nothing is salvagable. But yet i pulled the Autronic cdi out cleaned it off. Sprayed some wd40 on the pc board since it looked like ****. Cleaned up decent. Pluged it in to another car and it fired right up..

Then you got the AEM which if there's a full moon out or maybe your using the wrong spark plug or wrong battery or can't start it up when cold or the wrong coils, they seem to burn up quite easily..

Heck no, no racing on cold days... but you still gota start the car on a cold day to head to what a burger...

 

AEM is aware of the problems most encounter and are working hastily to repair the broken units. Mine was repaired in less than two weeks every time it broke.

 

AEM deserves everything you guys are shelling out about the old C2DI ignition issues. There were flaws in several production runs that caused entire batches of faulty units to be shipped - this is why you hear that some people had success and many people that didn't. Since so many units were sold, it took a while to figure out the pattern of failures and determine which groups of units were faulty and why.

SpeedDreamz is correct - AEM is standing behind the failed old units and has been replacing them with updated units when customers call.

The new AEM Twin Fire CDI is a different story. It is a completely redesigned product new this year with an extremely minimal failure rate to date. We've had thousands and thousands of hours of field testing dozens of units with racers, shops, and enthusiasts long before this version was released.

That being said, I know it will take a very long time to regain everyone's trust and confidence in the ignition line. I also respect anyone that won't bother again because of the previous product.

I second that, DEVIN'S the man

for Devin's post, pretty stand up right there. Devin is one of the ones that spent allot of time fixing our problem.

Considering the gap and boost levels we run I would say the box is doing plenty of work... Definitely not junk.
