Tuning guys...'puter question inside.

[KATwo40]

Well, I have an opportunity to trade my ol' dirtbike for a Haltech E6K. (Bike is valued around $1,000....really hate to do that because I'll be out of a bike, but whatever).

The E6K has the 3 bar MAP sensor and is currently wired for an FC (RX-7), but I think I could easily re-wire for the 240.

Any negative issues with using an E6K on a '93 240sx? This would be an excellent tuning solution for my 400whp build. It has all the auto-map features to make for an easy start when on the dyno (less time = me happy).

Is the E6K with upgrades worth $800-1,000?

Also, would the E6K be better than MegaSquirt2?

Thanks in advance.

C'mon, no one has any help on this?

Haltech is good, but will require a lot of your time to install and setup correctly, not to mention tune. If you want plug and play, the only unit available is the EMS and runs for about $1500 for the base unit.

Something that might be of interest - http://www.frsport.com/information.php?info_id=9 - Powerfc with map sensor pushing around 280 rwhp.

Thanks for the input.

I sent an email to FRSport.com about the board.

How much does the PFC usually cost? There's no way I'm gonna spend $1500 for that AEM computer. Yes, it's neat and is plug'n'play, but that's just silly. I'm not afraid of some wiring.

Interesting trade offer.

I'm not sure if the Haltech E6K is worth much more than a grand, I would look into it. I'm mostly talking out my a$$ cause I have no real experience with the system lol, but I'm pretty sure that the units themselves are universal but require a ton of custom wiring to make them work for specific applications. You might need an adapter or something for it to work in the 240, and honestly I dont think I've ever seen one of these systems installed in the S13 so you'll pretty much be on your own for tech support. To me, $1000 seems kinda steep for a system that will require so much work and is at this point mostly unknown with our platform.

It does have the possability of bieng great, though. Haltech is well known and works great for other cars, so if you can get through the (probably huge) initial pain of getting it to work, things will probably be great from then on.

I donno man, research the price and see what you find out!

people tend to forget (or just not know) the real cost of a standalone.

first there's the sticker price + matierials (wires, sensors, connectors, etc...) + dyno time...if you're lucky you'll be able to find someone who has experience in whatever system you have (an hour or two of dyno time)...if not, then add a snickers bar to the price cause you're not going anywhere anytime soon.

$1500 is dirt cheap for a standalone that's uses your stock wiring harness and sensors and has a base tune to get you started, and i'm pretty sure you can get it for cheaper than that if you shop around. you'll double the price of the aem with another system if you're not careful.

If you're worried about plug and play then you need to just toss the MSEFI idea out the window. I'm pretty sure the MSEFI is as far from plug and play as you can get (well, maybe you could design your own EFI system... that would be worse). But as far as cost for a standalone, I don't think you're going to beat MSEFI anywhere.

No clue on the other... I'm going MSEFI

Everyone keeps insisting that I'm dead set on plug n play. I'm not really so concerned about that, nor am I afraid of some wiring and tuning. I simply wanted to know if anyone knew of any hangups in adapting to the stock harness, or any drawbacks as far as the system's tuning capabilities.

What I've learned on another forum (very good tuning forum) is that the E6K CAN run the 240sx, and use the optical ignition we have. Also, it can run a wasted spark system, but it has a drawback. Either you have to run batchfire OR wire in an RX-7 ignition module (from an FC body) that has the toggle on-board. Then set the E6K to run toggle and you still get sequential injection with wasted spark. However, you cannot run sequential injection AND sequential spark at any time.

I'll steer clear of this system, as I really don't want to source all these parts and pieces to make it work. Additionally, the software samples I found on the Haltech site show it's tuning screens as linear graphs, as opposed to 16x16 tables. I'd rather use the table format, but that's just personal preference.

The E6X is supposed to be the bigger/better unit, lists for just over $1,000 and has the same quickmaps (plus a few more) feature as the E6K.

So, there we go. Thanks everyone for your input and suggestions.

Dis batchfire if you want, but you have to realize at high engine speeds it doesn't matter since the events happen so quickly, sequential basically becomes batchfire.

This is very true. However, 740cc injectors idling at batchfire MIGHT make for a bit of a lumpy idle and closed loop operation. I'm not willing to take a $1,000 guess on whether or not it will...are you?

[Florida240sx]

Fell lucky? tkae a gamble lol. Good luck with whichever way you go.

interesting article about using a pfc on a ka, i had always toyed round with the idea of grabbing a hacked up s13 sr harness and converting a ka over to the sr harness, thus gaining a nice dis system and the ablilitity to plug in a powerfc dejetro.im curious how they did the spark bit, thats proly why they needed an adaptor board since the ka uses a dizzy...

Save your bike and go with MSEFI..

The debate between sequential and batch injection is overblown. In order to take advantage of sequential in respect to intake valve opening at idle with your large injectors, you will need precise wheel decoding of the nissan CAS. I know of no standalone besides REYTEC that does such a thing, haltech certainly does not. It uses sequential injection in a rudementary form, there are 4 injector channels, but they are not in full sync with engine events.

With the addition of the router board, MSEFI will. It will have sequential injection and COP support as well. You will be able to fine tune injection/ignition to 720 degrees of engine "events", as precise as you would like.

Most well known toyota engines such as 4age's up to 1994 (I think), used batch injection. All 16v 4age's did, you would be quite surprised.

Well, I installed a Fx10 on a Honda (sorry guys, needed the cash)Was a completly pain, nedded all the sensors (uses GM sensor types) and no ignition control. Basically a wannabe stand alone with no ignition.Dont want to imagine how this ECU will work on a 240sx, let alone the wiring. You better save your bike and buy an emanage or save for a real standalone, either AEM or FAST (worked great on my GN)

[Chezedik]

You should have told him, "That's called emanage."
