Oh, trust me, I have seen it all. In order to certify to the microminiature level that I work at, I have to attend 2 months of school then recertify every 18 months. Some of the CCAs and things we get in are amazing...

 

Hey, I demand you start a thread in the lounge and post pictures, this I want to see


You'd probably go off on our prototype MegaSquirt harness, it's full of garbage, running speakerwire everywhere and such. But hey, at least it is soldered and heatshrunk

As stated, it's a prototype, we are redoing it for real soon, and tearing out the stock ECU harness entirely.

And hey, cuz of our monkied harness, everyones got trailing ignition to muck with! Ha!

Anyway, back on topic:

I will also throw in my vote that you go with what your tuner reccomends, especially since you are not tuning your own car.

But if you were tuning your own car, I would then HIGHLY reccomend the MegaSquirt.

 

Yeah, just took a 16 week solering course where I got a PACE certification. I believe it was Advanced Surface-Mount and Through-Hole Board Repair. One of the main reasons I'm getting it because I love projects like that.

 

Not changed much? 80's technology?! Dude, what rock have you been hiding under? Go and look at their current line-up before you make crazy, silly comments like this. There are plenty of rotaries running Haltechs too, and lots of support for them.

And drag racers are about the last people I'd mention when comparing EFI systems. Ten seconds (or whatever) at WOT shows practically nothing about the abilities of a particular system. Notice how few top-end EFI systems like MoTec or Autronic you see in drag racing? They're hardly used because their extra capabilites are simply a waste of money on a drag car. MicroTech is cheap and simple, hence its popularity in drag racing.

That's completely wrong. All the Rtek chip does is apply a mulitplier to the >3800rpm fuel map to get the mixtures back to stock when increasing injector capacity. It does not allow you to do any tuning, which is one of the main reasons for getting a fuel controller. There is no reason why they can't be used together, and you will always get better results if fuelling is properly tuned rather than sticking to conservative factory mixtures.

 

With the Ultimate you can get rid of the AFM, and run completely of MAP. The system is more comparable to a standalone than anything else. Even with the old blue unit, suposedly in Japan tuners found a way to get rid of the AFM; however ive never been able to find the info. But for the price the Ultimate is an amazing system.

 

Woah! Okay, now. I'm still fuzzy on the whole megasquirt thing. I know it's an EMS, but I still don't know any details on how it operates, if it's a piggyback or complete standalone, Hell, I still don't know where to find the bloody things! If somebody could direct me to a thread about this or a link or something, PLEASE DO SO! I feel like an idiot right now because I've never thought to ask when it gets brought up, yet I've researched the other "mainstream" standalone setups as much as possible before deciding that the E11 did everything that I wanted it to do. Mainly I'm looking for closed loop running off of WB o2 all the time, just change the AFR maps per my desired "application" (i.e. racing, street, emissions, etc.). The big thing, though, is that I don't think that it's really too much to ask for that, is it?

Well see what you did now!? Change my mind will you all...

Anyway, the ignition module on MS3, does it run off of the stock coils and CAS, or do I have to do something completely different? Also, I think it was wanko who said that the leading coils stop firing over 5k RPM or something like that? Is there a known way to avoid/correct this?

 

I don't know where you got all that info from...

First off, there are 2 ms boards, v2.2, and v3. Either of them can be used with an RX7, but you have to modify the boards differently to make them work.

Second, the fully stock 2nd gen (and 3rd gen should work too) ignition works fine all the way up to 9000 rpms (that's the highest we've tested, it'd probably work higher).

There's no need to avoid/correct anything. Just mod the ms board properly, install a version 025k or later of the msns-extra firmware, wire everything up, and you're ready to tune.

 

The Rtek chip does have other features that an S-AFC doesn't provide (FCD, ignition retard above 9 psi, lower secondary staging, etc.) which make it a good combo. I was thinking more along the lines of purely fuel adjustment, in which case an S-AFC would be far superior and there would be no need for the Rtek.

I guess what it comes down to is that if I were spending $300 to $400 on the S-AFC combo + Rtek, I would just buy an e-manage ultimate or Megasquirt. But I guess if you want a simpler setup, the S-AFC and Rtek is a good choice, although there are better choices for the money IMO. I should have made that more clear.

It seems we're going to have some great, inexpensive alternatives with the MegaSquirt & Spark and Rtek 2.0...

 

Please refrain from making such false blanket statements.
You realize stuff like this can get you banned?

Can anyone CONFIRM this???
Right now, it's all myths until someone confirms this is possible.

First I hear you can do a "hotwire conversion", now it's a MAP conversion???

And no, no one has used the old eManage to get rid of the AFM, so stop spreading myths!


-Ted

 

there's a lot of confusion about this and no one has yet given any straight answer. i think we need to call up Greddy and ask them

i DO know that with the e-manage you can swap your stock AFM with a similar-type AFM out of another car. this may be confusing some people into thinking you can get rid of it altogether.

what i HAVE heard that sounds reliable is that you can use a Vein Pressure type controller (similar to the one HKS makes), but i don't know if Greddy is going to release their own anytime soon or what.

 

Airflow Output Map - Previously labeled “Airflow Adjustment Map” is now “Airflow Output Map”. This can now used to eliminate the factory airflow meter. This is done by directly inputting voltage or frequency in to this map.

You can do either one. Heres all the specs.

Um, that doesn't go into detail on how you do it to an FC3S...
