I lost a lot of power when I installed the mazsport coils. I didn't even really notice it that much since it's hard to tell as the boost kicks in.

It's possible you have the same issue, even with the dwell changes.

Here's my before (blue) and after (red) dyno results.



You really need to hit the dyno too, and see what your car is doing, otherwise we're just randomly speculating.

 

My OEM coils I removed were working perfectly.

Maybe I will swap them out and go back to the track.

 

I'm sure the mazsport coils can function as advertised, but after dropping over $500 on it, I ended up making less power than I did with the stock greddy kit.

If you do several dozen dyno pulls when tuning, it's cheap, and costs less than $10 a pull. But when you go in and do just one to see what power levels your car makes, it costs a lot (the red chart above cost me $70).

I'll be damned if I have to sit around tweaking maps, and trying to tune something that should work out of the box. It's one thing if this tiny tidbit of information was made aware to me before I made the purchase, it's another to find out afterwards.

I'm not even going to get into the detonation issues that resulted from not having the proper dwell settings (before we knew there were dwell changes needed). Two detonations at 11 psi isn't something to laugh at.

 

Ouch.

So it safe to say the Mazsport ignition solution works fine on N/A but not FI.

I can’t wait to remove them now. I am anxious to get my HP back

 

I don't know if I would go that far. But it does appear to require tuning to function.

I should be getting BHR coils next month (they just need to produce brackets). No tuning needed, no ignition box to install.

 

I better get on that bandwagon asap. lol

 

Did you use the maps with the correct dwell settings when you did your runs ?

This surely must apply to get max benifit when running N/A as well ?

 

no, NA vehicles don't need to ignite as much fuel as my car does.

You can see in my graph the results were actually a bit better till around 4.4k rpm, then it went downhill quickly.

 

Jason you can't really use your dyno chart for comparison because you were using the Interceptor-X when you made 300rwhp and the AP when you didn't. I would love to see someone post a actual dyno chart, on a dynojet, with the AP and a greddy turbo kit. I have spoke to several customer reporting less power with the AP than the Interceptor-X while running the stock coils. I have not said anything because I had performed no testing, had no proof one way or the other and frankly it didn't make sense to me.

I have been to the dyno with the AP and a turbo kit same AFR's, same boost levels, same timing and made 26rwhp less with the AP. Yep, uninstalled it, plugged the Interceptor-X and in three runs had a 26rwhp increase, WITH STOCK IGNITION!

Called the guys at Cobb explained the situation and they couldn't explain it either.

It's not the coils guys, I eliminated that as a variable myself during testing using new factory coils with about 2 miles on them.

I am not trying to start an argument here but something doesn't add up.

Does any one with a Greddy turbo kit have a dynojet dyno chart?

 

Yes, it's true the difference between the two was the fuel management system AND ignition coils (the 300 whp run with int-x and stock coils vs 260 whp with AP and mazsport ignition coils). However I can say that the moment the mazsport coils were removed, my car quit having significant issues with acceleration and bogging. Both of which were present on the dyno run that made 260 whp.

 

btw, Scott, who's FI AP map did you use?

 

^ Cant say one way or the other there Jason, maybe something got hurt when they were plugged in incorrectly. Pm me the name of the guy you sold the system to and I will dig deeper. Actually it might be a good idea to have him send them back for inspection.

 

My own with the assistance of Cobb tuning.

 

If anyone running the Accessport with a Greddy turbo kit is local, I will gladly pay for your gas and the dyno charges to come over and provide some results. I will also be happy install and uninstall our ignition system on the spot to put that myth to rest as well. Thanks, Scott

 

I didn't want to get into this, but ..


When the coil harness was plugged in reversed (essentially the spark plug was controlled by the wrong coil), the car didn't even start up (Remember, you were worried about it flooding?). The coils were just firing in the wrong order (if they were even firing at that point) and nothing happened, so it's not like I drove anywhere with it or went into boost with it. All the electrical components on the ignition system was plugged in correctly. One of the ground points used differed from your instructions, but I swapped it back and forth between the two and there was no difference between it. My ground point was connecting to the batt negative terminal, later I used the recommended chassis point (which was connected to the negative terminal of the batt by a grounding kit, so same difference).

It wasn't till it was all plugged in properly that I tested it out and shortly after had issues with the detonation. I thought it was the mazsport coils messing with the AFR that somehow caused it. Thus all I would need is for the int-x to be retuned, right? So I stuck with it, and had you street tune my car for two hours to fix the perceived problem. You also went over the ignition setup to make sure they were plugged in properly, and found no problem. But immediately after the street tune, I had another detonation event on the drive home! The interceptor-x that ran so nicely for me for over a year, I thought had to be the reason for the detonation. After all the coils were brand new, so they *couldn't* be the cause. That's why I sold the int-x. It was causing me just as much headache as the emanage ultimate that preceded it. However the issues remained even with the AccessPort. It wasn't till I relented, and removed the coils from my car that the problems cleared up. I could accelerate, I could WOT in boost, I could drive like my car was OEM again and had zero problems. The gain in power was self evident within minutes of driving the car.

Then, the unthinkable happened.

Last week when I was getting new tips installed on my turboxs exhaust, I found why my car was leaking oil. It was traced to the engine itself. I'm not going to lie, I blame the ignition solution for my front iron housing cracking. There's no way to prove it, but having two detonations at 11 psi makes it the most likely culprit in my mind. After all, you only need one detonation to completely destroy a rotary engine. The engine still runs nicely, however the oil leak from the housing cannot be ignored. It loses around a quart of oil every 50 miles.

You're a good guy and I have no problem with you personally, but I didn't sign up for anything like this, and I don't like what it's costing me to have my engine rebuilt.


Then your findings wouldn't be directly comparable with the maps most of us are using from Jeff.

In about a month, I'll hit the dyno again. AccessPort, with either stock or BHR coils, and we'll have something to compare with. Hopefully someone in the meantime has some results to share with MM maps, since any results I have will be tainted from so many things on my car changing between the dyno runs.

 

Jason, I am sorry to hear of your engine failure but the Mazsport Ignition DID NOT cause your front side housing to crack.

I have seen many engines, with much thicker castings in the dowel area fail over the years and it's an instantaneous failure. Your failure occurred weeks after you uninstalled it.

 

The crack could have been present long ago, but proceeded to worsen as I drove the car (Oil is under 80 psi or so?). This would explain why it was not noticed till it started dripping oil on the lift. I wouldn't have even bothered looking for it if it wasn't for the muffler shop guy freaking out over it while it was up in the air.

Even right now, the crack is not so bad that I cannot drive the vehicle. The underside of the car is covered in oil though.

I suppose I can test this out by driving the car around and seeing if the leak worsens.

 

**** a brick !!! that is a bad oil leak . Sorry to see that - seemed like you were just getting your car perfected too ......

 

welcome to the world of engine modding ....

 

btw, so the timeframe is illustrated, I removed the mazsport ignition coils May 3rd. Two weeks later (17th) is when I found the leak. I don't drive my RX-8 every day, so an oil leak even as big as the video above, wouldn't be apparent to me immediately, as can be evidenced by my finding out about it only when the car was up on the lift getting new exhaust tips installed.


Yeah, you gotta pay to play. It doesn't mean I have to be happy about it though.

 

Sorry to hear Jason.

Maybe it started as an internal hairline crack and only opened up over time?

 

has happened before. i think the guy was in south africa.

beers

 

is there anything you don't know swoope ?

 

i learn here.. have you adopted me yet???

btw.. first track day. big fun.. bad news. i was driving a car set up for auto x or drift..

last session. coils failed, but i could put the car where i wanted it..

the only analogy i could use is i was on slalom skis on a gs course.

but big fun..

beers

 

WOW. Very nice offer.

I so wish I lived nearby.
