cyclone ecu ?

[dsm908]

ok guys so far i've checked the other threads on the cyclone topic but none seem to answer my question. i currently own a talon tsi and i blew the motor due to driving in jersey but my question is that im going to put in a jdm motor in my car it comes with full harness, but do i need this and/or do i need the jdm ecu ? or can i simply use my stock tsi ecu?

You will reuse your stock harness, ecu, and any sensors that may be missing or different on the jdm engine. And to the best of my knowledge, the dual board jdm ecu wont even work in our cars.

Perfect timing with this thread. I'm at the same point. My JDM engine is here, cyclone and all, and I'm curious about this. I've tried searching and found a dozen threads on how to actually make the cyclone actuate properly at 4200 rpms without chipping the ecu and all that gravy stuff.

If I use the stock USDM ecu do I HAVE to get the sucker chipped and all that, or whatever? I have a really good detailed listing I found off this forums or dsmtalk that has really good instructions with pictures, but it doesn't say whether or not you need to actually use the JDM ecu when it actuates properly. Just how to hook it up so the butterflies actuate. Can anyone clear up that little bit of fog? I really want this sucker to work right, the first time. And since I have the JDM ECU and uncut harnesses I want it to be as pain free as possible, for both me and my wallet.

thanks for the info, but whats this problem im hearing now at 4200rpm ?

IMHO guys using a JDM engine should consider it a longblock and move their intake, TB, coils, injectors, fuel rail, sensors and harness over so you don't have to start hacking the car to make the engine work. Make the engine fix the car.

If you really want to run the cyclone intake then you should have a EPROM ECU and chip to run a solenoid to activate it or set up a RPM or pressure switch and understand the limitations.

Yep i agree if you are going to run the manifold you should do it the way it was meant to work. its a great manifold as long as you use it properly

IMHO guys ?? lost you there from the begining

In My Humble Opinion people should strip the JDM engine down to block and head (longblock) and then use the parts from your existing engine to put it back together and into the car.

ok cool, so your basically saying that not to try with the cyclone IM, just use the head and block, then whats the point of a jdm motor if you dont mind me asking am i missing something

You tell me what the point was.
In the cases I know of it was to get a working engine cheaply and quickly. Having to deal with the unsupported manifold or with what often turns out to be '90 style ignition parts and harnesses causes problems, makes it more expensive and takes longer.

yeah your right on that perspective thank you very much i also got an amazing deal at least i believe so, jdm motor and transmision transfer case new 16g turbo act 2600 and fidanza flywheel with wireharness and alternator and ps pump for around 1.5k which i think is a good price? do you beg to differ ? or

 

[mach4g63t]

Where'd you buy it for at that price? Was it shipped? I can find them for that price, but mostly in Cali and shipping over to the east cost is pretty pricey.

And... is the JDM ECU in an eclipse an absolute no-no? if so, why? Are they only useable in the GVR4's?

Just like that there is more than one US ECU there are more than one JDM ECU.
While the connectors are the same several of the pins are used to different signals/functions and internally some use the same ECU architecture and some like the dual board ECUs are completely different. Then there is the software.

So unless you know exactly what your dealing with you are just asking for trouble.

None of the JDM ECUs are a direct swap for a US one.

Keydiver is the closest thing to a expert on JDM ECUs and much of the discussions on differences can be found on the Galant VR4 forum.

[dsm908]

Ok great thank you for the information. I'm going to just use the long block as you insisted, perhaps in the future I will try the cyclone intake manifold, but for right now I'm going to just get it running first.

I found the motor from some one in Utah, he used to own a shop and someone did'nt finish paying for the motor, so he put it up for sale. Now its mine !
The asking price was 1.5k and shippin commercialy was 250 so full thing for under1.8k

 

[dsm908]

Ok I just finished looking at dsmchips and they are stateing that i can use a FPR to control the cyclone intake. Good idea ?

Sure why not?
If you have questions about using the cyclone intake with a DSMChip, then Jeff (Keydiver) would be the best person to ask. He has a forum for you to do so.

Cool great thank you very much you've been a great help all of you thank you

no ## stock ecu will not open the sylenoid in the intake on the jdm last summer i putt a jdm cylone engine in my 99 gst ## gna have to change over the harness and get the jdm ecu or its gna be a waste to even do the jdm swap.. get back to me if u have any questions

Will using any of the alternative methods to actuate the cyclone-- rpm switch etc-- be sufficient on the stock GSX ECU? You said the JDM ECU is a no-no, but what if you don't have an e-prom ECU? Can you still hook it up to actuate properly without chipping the board? Or will the engine not run right?

I too have the exact same question, as i recently bought a gsx with cyclone intake and E-prom Ecu. Ecu just burnt out... will a standard ecu work??
