Getting my high compression stroker h22 ready for some tuning this week, been out of the game for about 10 yrs and wanted to know what's out there now. I use to use a hondata s200 and never had a problem. Was wondering if I can still use this or is it obsolete. And if so what would be recommended for this application.

N/A 91 crx with 2.7lt stroker, 13.1:1 cr. Any advice is appreciated!!

 

S200 has been discontinued since the beginning of '08 so i'd say it's a little outdated. lol If you have someone who can tune it, i'm sure it would work though. I'm using S300 V3 and am really happy with it but I know there are a lot of good options around like Neptune and others. Just depends on what your tuner is comfortable with.

 

Aem v2

Hondata is the ricer engine management nowadays

Tuners like it because its easy to tune and gets you out of the shop fast and money in their pocket

 

Sure, listen to the guy on engine number 672.

 

talk to your tuner. Not the internet.

 

High comp 2.7l i wouldnt trust a oem based ems .

 

yes it'll be fine...of course there is better stuff out there but...the s200 is simple enough...I was doing chips for setups like this about 15-20yrs ago lol so its fine.

 

Different engine management systems have their own benefits, and you have to decide which meets your needs the best. Don't forget, as 98vtec said, to consult your tuner first and get his opinion. Your tuner will get the most out of your engine using the system he is most comfortable with.

The AEM V2 is fast and has a lot of features, but it lacks polish. It is more suited for a race car since it lacks the ability to alter the tune for different driving conditions, nor does it have any OBD based diagnostic capability. This makes this system a poor choice for a daily driven vehicle, but a solid choice for a race car.

Fewer and fewer Hondata dealers are tuning the old "chip" systems, so you may consider upgrading your s200 to a new s300. The cost is only $400 plus shipping and you will have a solid system that is ideal for a street car and will perform well compared to many universal entry level systems like the AEM V2... certainly in your application.

Just out of curiosity, how exactly did you get your H22 to a displacement of 2.7 LITERS ???

 

Lmao the v2 is GREAT FOR DAILY DRIVING

Much better than hondata in my opinion when you know how to tune all the tip in settings and adjust for throttle body sizes

Hondata can do it but not as precise as aem. Hondata is like a one size fits all.

 

My buddy's doing mid 9s on s300


BOOM ROASTED

 

Any ems can tune wot. Moot point. Add fuel, timing, boost the car will run.

I see No point running s300 if you add in bbg, traction control, cop conversion etc. the pricing is the same in the end.

 

Running and driving like stock and its ability and ease to accomplish that are more intuitive descriptions of ems ability and in the end it doesn't matter. You can have the "best" ems on the market and if you don't know how to use it, a crome or uberdata tuner could make it run better.

I know for a fact I can tune Neptune 100x better and make any engine run 100x cleaner and smoother than I could with AEM simply because my experience with AEM is very low.

 

Yup exactly my point.

Aem has a steep learning curve.

Once you get passed that you realize you have complete control over everything.

 

Complete can also be an arguable term. There are a couple well known tuners, programmers and general electronics geeks who would disagree

 

turbohatchy, did you forget about diagnostic ability ??? The AEM does NOT have OBD function. I do not understand how you cannot see this as a distinct disadvantage for the AEM with respect to daily operation and simplistic diagnostic capability for the average end user when compared to a system like Hondata or Neptune which uses the stock ECM platform foundation.

 

Why do you need diagnostic ability? I assume you're referring to smog checks?

If not are you referring to the check engine light?

If you know how to use a laptop its easy to see what all the sensors are doing.

Easy to see what injectors are firing, what coilbis firing etc.

If you have a problem you can datalog i think almost every channel or close to it

If you cant do any of this stuff then you need to pay someone to do it.

Although aem has a 200 plus page manual that walks you through everything. Their tech support is also pretty good. Call in to aem and theres a couple guys that are always willing to help. Ping from aem is the most knowledgeable with hondas

 

On Board Diagnostics are just that turbohatchy... a system to help quickly diagnose problems with engine operation. With an AEM system running your car, the "Check Engine" light will NEVER come on to warn you of a detected problem with the engine. OBD is NOT about passing emissions testing... that is a ridiculous statement.
You have to understand that many people enjoy high HP cars but have little understanding of tuning... and may not be comfortable analyzing data stream to help locate/isolate an engine problem.

Here is a REAL example that may help you understand the benefit of OBD.

A Honda owner with a moderately modded N/A engine is on vacation at the beach... 6 hours away from his local tuner. The car starts running poorly, and ultimately stalls and will not re-start. Finding no local performance shop that can help him, he has the car towed to the local Honda dealership. His '95 Civic has an AEM V2 installed... how will the Dealership diagnose his problem and ultimately, fix his car ??? You and I both know that they will probably turn the car away... however, if he had Hondata or Neptune, the OBD system would still be functional, the technician could check the engine codes, and then rapidly diagnose and fix the problem.

I agree with you that different systems have strengths... rapid diagnosis is NOT one of the strengths of a "stand alone" system and you know it. Even being armed with the knowledge of being able to examine some data stream, this process is far slower than OBD... not to mention there are so many real world conditions where one cannot get a datalog to examine because the engine quit and won't restart. I know of VERY FEW individuals who keep a laptop running in their car at all times datalogging just in case there is an issue... and I know that you aren't that stupid to think otherwise.

Just because you own a product doesn't make it the best one available... and it is time you admitted it. Saying another product is garbage because you DON'T have it is silly. I have given you empirical evidence to illustrate how wrong you are and offered real life examples to support my argument... and you have only offered opinion. You are wrong... accept it.

 

The only thing hondata will help you diagnose are sensor problems. What else is it going to help you diagnose?
Aem is simple
Ect
Vtec solenoid
Injectors
Distributor (tdc,ckp,cyp)
Iat
Tps
Map
Iacv

Thats it. If you have a problem you just check all your wiring one time and if everything's fine youll see it on a data log.


Does hondata have any low fuel pressure protection? Knock control? Individual knock control? O2 lean protection under certain load points? Coolant temp protection?

No one gives a **** about a car stuck 6 hours away. Find a better tuner or stop building half assed rattle traps.

Ive owned s300, moved onto aem.

Went back to s300 and realized what a **** system it is.

To say because hondata has a dummy light on the dashboard its better in every way, well, thats just obtuse

 

it operates using the factory OBD. so you get all the check engine light and trouble codes the virgin ecu could do which does ultimately make it a lot easier to troubleshoot.

Hondata has lean protection and overheat protection. You have the ability to add analog/digital circuits and I believe you have the ability to set warnings for them.

If you are asking questions about what a system can and cant do and arguing that its "crap", I would recommend learning what the systems can actually do before entering a debate. Just saying. I know how amped you like to get.

 

I know what hondata can do. Its not a secret

Aem just does it better

The dummy light on the dashboard is not a very good reason to stay away from a system. If you wanted you can make aem do the same thing. Theres triggers for every parameters.

Like I said if a sensor failed, you wouldnt be stuck on the side of the road. A major engine problem will leave you stuck.

 

Dont even get me started on flex fuel either

 

"Neptune/Demon RTP Hardware/Software Combo" [NEPTUNE] - $399.00 : Moates.Net

"Sensor Adjustments For Altering Fuel, Ignition, And PWM Duty Cycle Based On An Analog Input. This Means Support For Flex Fuel Sensors, Traction Control, PWM Boost Gain Control, And Other Specialized Features."

 

What about adjustments for cold starts? Complete separate ign and fuel tables?
Flex fuel Idle control?
Theres more but i cant remember off the top of my head.


My main point that i dont think is getting across clearly is this.


Add in the ems plus bbg, traction control, cop and you are damn near the cost of a full stand alone which offers the same features and more.

 

Oh one other huge feature is boost comp tuning

If you dont know what that is and microsec/bit look into it

 

the features are already there. does aem come with coils or epm? no. does it come with traction control hardware? no. does it come with bbg hardware? no. they are all additional cost options on top of the cost of the ems.
