it wouldn't hurt and it would help on the install with less tools to use like jujo said

That's a good idea. I crimped mine so i thought it was really good and tight and it wasn't. The wires slipped out and i had to pick up another one.

I can't remember if i posted this here or not but my car was flooded when i got my coil kit. Well, i finally got it running tonight after many attempts and all i can say about the BHR coils is wow!

Every improvement is subtle but a significant improvement over stock. So far i've noticed that the engine runs smoother and quieter, it idles rock solid and the power band is smooth and buttery and full of POWA! There is not a doubt in my mind that my engine is running at it's full potential.

Nice job guys.

Hey guys I need some help diagnosing a problem, not sure if this has anything to do with the ignition install but a day after and this happens to me here

All suggestions and help are welcomed

alienRX8

Ok so I bent the engine hoist a little so it would not mess with the cables and let me tell you the car feels different hehe. It hasnt shown the same symptoms yet so hopefully its fixed. Now I think I need to retake datalogs because the AFR's under load/boost have changed

I installed mine this weekend and I also forgot to unwind the cable BEFORE getting the bracket onto the studs. No big deal though!

The biggest issue I had (of all things) was getting the nuts back on, with the BHR bracket installed. I was able to get the 2 rear nuts tightened, but I could not get my fingers down there to even hand-tighten the other two. Any suggestions on how to get those other nuts on? Or better yet, tightened? Right now the bracket is very secure, but I'd just feel better with all four on there.

As for impressions of the new coils... the most obvious improvement is in the idle, which is now much steadier. I'm hoping my gas mileage improves as well (also installed new plugs), because like the idle, it's been abysmal lately. Charles and BHR, thanks for making a great kit -- it was worth the wait!

I finally got a chance to install the coils last night. Everything went well. My car started right up after installed. And this morning it started right up and I drove to work. Then time to go home, I went out and started my car. It took 2 cranks to start it up. So I drove home and shut it off. Then I started up again, now it took a while to get it start up. I did it a few times later, and same thing. Took a while to get the engine start up. Anybody knows what could be the problem. I double, triple check the coils and wires. Everything looks just fine. Any help?

You need to change you battery or your starter (04 starter?) is showing signs of it crapping on you.

Or could it be the battery on it's way out?

fannin522

im having same problem after i installed my new coils and plugs idk wat the deal is either i checked everything

bse50

Same deal here but i have weak battery

fannin522

so i guess its a common thing mabey its time for a new battery or something ill have to check into that because after it starts it runs perfect much better now that i have the new coils in and idles so much smoother so i will have to see i guess

pking1122

I'm starting to think that mine may not have been installed correctly or something. I noticed that my MPG has gone down, and sometimes it take longer to crank/start. Anyone ever experience this?

bse50

Nope, my car runs fine and i have a better MPG now.

I had the same problem this Winter after installing the coils. I replaced my starter and battery and have no problems at all. The ignition kit isn't the problem but your previous, failing coils may have been masking the starter/battery problem that plagues early model RX-8s.

If you still have it under warranty you should be able to get a new starter from Mazda. If not you can either get a reman from Mazmart or try to get one of the few new sets left out there. Mazda no longer makes the upgrade starters and now only offers remans.

Also make sure all of you have the kit grounded properly. That can cause some of the issues you're reporting.

fannin522

so i should get a new starter? im under extended warranty so i might try to make them give me one and also it had some trouble starting before i put them in but not near as bad as after i put them in

Nothing definitive. The starter and the coils really shouldn't be connected which was something it took me a while to come to grips with. The only thing that Jon, who's one of our resident electricians, could guess might cause a problem is if the new coils were drawing more current causing the starter to not have enough to spin up as well as it had previously. If you have a very strong battery or a very strong starter you shouldn't be affected by this but if you have a weak battery and a weak starter then you might see the 'slow start' affect get amplified in any reduction in current. And my car was starting every time but it would usually take a 7 second crank, followed by a stop, followed by a short crank which would catch and start.

We did take apart my starter after replacing it and it looked like only two of the four contacts used to spin the motor were fully extended. Jon may be able to explain it with better terminology since I'm just a DIY tinkerer on my car and hate the thought of ever having to understand electricity. I just like plugging things in and letting the magic happen.

Yes. Get the new starter. Try to get the upgraded starter if possible but they may only get you a remanufactured one. Anybody who's got slow starting should try to fight this battle because it -is- the starter that's ultimately causing these issues.

Here's a post on my starter diagnosing including a video of my starter cranking (and failing) with my 04 starter and Diehard battery, then the Optima, then the new starter.

ya wow thats a huge difference ive been wanting a optima red top neways so ill prob get that but how your car sounds at the veryfirst is how mine does so ill start with a new battery and then take it to delership and see what i cant get done thanks man

I'd agree but that's the only possible thing we could come up with that might explain it. It's hard to believe that the starter would be that sensitive to any change in available power but I guess the early starters seem to be able to accomplish the impossible - at least when talking about finding ways to suck.

I'm still pissed off that my stealership never replaced it after two consecutive years of cold-storage where the car failed to start in the Spring and required a tow. Shame I didn't frequent RX8Club more back then.

I have not had this issue, the issue I did have was already discussed and after bending the hoist it appears to be fine.

well, i wanted to hold off on my review until i figured out what was wrong. i had marginal start-up before the bhr ignition, then after the ignition upgrade it would not turn over when warm. i swapped the starter for a used -not updated- one with about 20k miles. same problems persisted. i garaged the car until my new updated starter from mazmart arrived. what a difference!! it starts up within a second. turn the key and let go, no more cranking for 5-6 seconds.

i had to modify the bhr base plate because all the bolt holes were about 5mm to the left. the coil would contact the intake manifold and wouldn't sit properly. i couldn't tell if the baseplate was backwards or if this was just an issue on my unit, but it definitely would not fit without modification. once i enlarged the holes, everything fit right into place. even before swapping starters, the bhr ignition felt solid at all rpms. now, it's butter!!! great product bhr!

So I'm not the only guy who's having this problem. Well...I gotta look into a new battery and starter now, and spend some more money.

Okay, so you're saying that the engine wouldn't start up immediately after you shut it down (or when hot)? This is the exact problem I'm having now. At first I thought it was more of a random starting problem -- and I emailed BHR about it -- but now it seems that the engine won't start when hot. And btw, I also had very marginal start-up before the BHR system was installed.

I was about to make an appointment to get my starter replaced (under warranty), but I held off because I didn't think it would help. Why would the updated starter remedy a hot-engine startup problem? And why would this particular problem worsen after the new coils were put in? I've checked all my intake connections, plugs, etc and I guess the next thing would be to get that starter. I just don't understand the connection between the starter itself and the problem I'm having with only warm-startups. I am really glad to hear that it solved your problem though... hopefully it'll do the same for me!

Thanks for any ideas...

Charles, which TSB is the one that mentions hot-starting problems, specifically? I do know of the "Engine cranks no start" TSB, but this has to do with shutting the car down without letting the engine warm up properly. It shows the de-carb and compression-check procedures.

I also looked on Mazda's list of TSBs, but for some reason I'm not seeing it.

TSB 01-048/06

This TSB is not available anymore.

Hope thtat helps.
