I have done a search and have not come up with anything conclusive on what type of engine management would be best for the KA24DE with a turbo. I know the two routes that you can go, piggy back and stand alone. I have a few questions for each of the systems.

Stand Alone
Are there any Stand Alones plug and play for the KA24DE
What units have been used in tuning this engine
From those that have used them what are the pros and cons of particular systems

Piggy Backs
I was wondering if they caused the CEL?
Does the ecu relearn around them?
Would a single ignition and fuel system be better than separate piggybacks?
what are the general consensus on these systems
E-manage, Split Second FTC1
What about seperate piggy backs such as
Apex AFCII, Apex ITC, MSD Ignition control, Split Second Units

Thanks

What are your hp goals? If you want the ultimate in tuneability, you need to go standalone. The problem with piggyback sytems if that you are limited in fuel control and especially timing which is critical in turbocharged applications. I would go with a haltech because it is about as close to plug and play as you can get because it uses the stock nissan trigger. Hence, no custom pickups, trigger wheels, needed to be fabbed. Also, the software is very user friendly and easy to tune.

 

Don't forget a JWT (Jim Wolf Technology) ecu retune.

If you send him one of your injectors(for flowbenching iirc), and inform him of other specifics, he will retune your ecu (I think the name of the guy who actually does it is Clark Steppler....) and send it back to you, to run with the turbo, injectors, and whatever else you told him was in your set up.....

this is pretty conveinient, but theres no real tunability if your going to be changing your set up often, as you have to pay 100 bucks per retune, and theres a three day downtime....possibly four AFAIK........

 

I am hoping for a 300 hp daily driver and depending on how things go I may do a full KA24DE build for boost. The tunability is a major issue for me with the JWT. For two different setups I could have paid for a standalone. My main issue is I am trying to think ahead and get a system that I can use for whatever setup I intend to run. With the standalones I was not sure whether there was any support for our engines.

 

If i were to run 400+ hp standalone would still be better right?
I dont think i will be usign it for a daily driver when irerach this goal.

So there aren't any full plug and play standalone systems. For all of them the harness is going to have to rigged to go into the EMS. Is this correct?

the AEM system is about as close as you can get to a full plug and pray system.
costs 1300$ tho if i remember correctly.

 

The guy that got my Max running on the Haltech has done a few Ka's. I wouldn't go with Haltech mostly because it's pretty old school unless you get the E11 (I think that's what it's called). Another thing they closed shop in the U.S. so good luck on support. My tuner setup a KA with FAST/speedpro and he said it took him no time to get it running. just my .02
