This has been a topic in a couple other threads lately with the new release of hondata v3, so I figured I would make a thread and beat the horse dead.

From what it seems like after buying the s300, cop unit, and possibly their traction control, you're going to be spending just as much or more than the AEM.

Why are their multiple competitive sfwd cars on AEM and none on Hondata?

Is there something available for AEM that is comparable to Hondata's traction control thats helping these cars to go deep into the 8s?

im sure the people that have figured it out probably dont want to share, but if so, im all ears....

 

Everything s300 has AEM has. Besides the mobie data logging.

Aem has a ton more stuff than s300 tho for sure. The flex fuel option walks all over s300.

Also there was a threadmaybe a month ago with this same exact question

 

im not so sure about that

The main reason I like the V2 over the s300 is when you setup for C.O.P. you can completely get rid of the dizzy. You don't have to keep it for the cam trigger which is the downfall part in the first place.

 

I ran the AEM V1 many many years ago and did not like it, so I bought an
S300 in 2006 and have used it ever since. I do not know every single setup but I do know that Jake Blackman here in AZ was using Hondata when he was running 8.9's.

So Hondata is capable and can be utilized in some very fast cars, I know some other cars that run mid 9's and 9.0's using Hondata. Some of the bigger cars here in AZ like Aaron from TSR, Locash, Moses all use Motec.

So Hondata is proven to work in cars going as fast as 8.9's and for the most part guys wanting to go faster and deeper in the 8's seem to use Motec.
I also like the fact that with the new version of Hondata, you can send in your V1 or V2 and 250 bucks and they will send you V3.

 

Last big events cars in SFWD and All Motor that won were on AEM.

Motec 2-3 step sound sick tho.

 

I guess the big thing im trying to figure out is what people are doing for traction control on the AEMs. Seems like something has to be somewhat "automated" to control traction and make these cars that consistent out of the hole, but maybe I'm wrong.

 

hondata limitation of 4 injectors, the hondata ign retard just sounds different with the ign retard of aem (not ign cut!), hondata boost control is very undercomplicated - you can only do it by gear. aem is over complicated you can do it whatever you want. speed, tps, gear, all at the same time. hondata idle/iacv control is very very simple and easy to use, aem is super complicated. i guess for DD cars, o2 feedback in aem is better - never used them anyway.

and stand alone ecu just sounds cooler considering the price of the ecu alone, aem hands down...

but aem + smart coils + cam trigger/epm, maybe u have to consider what's in it for your application.

 

Hondata is not limited to 4 injectors people have been running 8 injector setups with Hondata for years.

 

Please explain how!

 

Just splicing the ground outputs in parallel, and wiring a new 12v source to the auxiliary 4.

 

The fast sfwd cars that run aem, are they using the v2s or new infinity?

 

Pro1 has been 8.8s on Hondata without traction control and at a local 1/8th race just went 137mph in the 1/8th with it.

Just a bit of info for those considering s300.

My big problem with Aem has always been hardware. Seems to be finicky. I've seen v2 guys have issues and get off of it because of that.

 

AEM lets you do a full system check before firing the car. Meaning you can run power to any sensor on the car without having to sacrifice firing it up and risking the engine getting hurt. You can also add sensors that are not on the s300. I've always ran s300 due to how cheap and user friendly the system is but AEM is better hands down.

 

thats not runnng 8 injectors...thats just powering up 8 injectors but driver is still 4 injector channels. I've used that too before switching to AEM. 8 injectors ON at idle is just nasty.

 

8 Id2000s on s300 here... Daisy chain them and cut fuel values in half runs great.

 

why the need for 8 2000s? did you acually run out of fuel with 4? usually i see 8 1300s

 

We have a car with a similar fuel system on 4 id2000s that's out of injector with a 50/50 ethanol/gas mixture on a fp67mm. my car is running e98 with a bigger engine/turbo setup so 8 was really the only way to go... I guess I could have done 1300s but I'm willing to bet I would have found the end of them pretty quickly. If your gonna run 8 injectors on hondata injector dynamics are the way to go I mean if you can make a car drive like it had a factory set of injectors with them then my logic said why can't I make two sets do the same thing if they are setup right.

 

RLZ just beat SF and they are running Hondata! Just goes to show they system does work well.

 

S300 V3 + Hondata Traction control = hard one to beat these days seems like.

I fought hard thinking about going s300 or AEM V2....

AEM kills the S300 in the Flex Fuel side of things. The new firmware on the V2 is pretty gangster, tons more logging etc.


But one thing AEM doesn't truly have is a Wheel Speed Based traction control like S300 does have. you could make one work in AEM though.

Idk for a Honda id take up S300 myself...

 

According to The Sauce Spot the car is on Motec...

 

Hmmm....That's interesting.
