I saw the thread on dsmtuners of how to rig the Cyclone intake to work on usdm dsms. Seth told me that sabzi and DOHCstuner have this setup on their Cyclone intakes with ther dohc. I was just wondering if you guys had any pics of it to post or send.

mine is activated by the ecu at 4100 rpms. i had Jeff O. at dsm chips install a driver on my ecu to utilze the egr circuit to drive a turbo eclipse fuel pressure solenoid to allow the actuator to open the butterflys at 4100rpms(same as the jdm ecu switchover point)
you can also use the egr circuit to trigger the actuator, but its not as effective it triggers them at 3000, cause you won't be able to boost while its only long runners(torque)
what kind of ecu do you have, i'm looking at trying to get an evo or gvr4 ecu, but not to sure where to look.
mine's a 94 eprom ecu that is i had socketed and rechipped with a keydiver chip.
www.dsmchips.com
eproms can be made to emulate any 1st gen dsm ecu.
vr4, automatic, jdm, cali spec, whatever.
same goes for second gen 95 eprom ecu's
but only 95 ecu's there are no other eproms for the second gen.
you say 94 eprom ecu, is that 94 galant, or 94 eclipse. if 94 galant, do all 94 galants come eprom ecu? how sweet that would be.
I'd just go out and take my ecu apart, but my car's at the paint shop. :roll:
Like the man said, most people run it off one of the egr components because they are activated around the same rpms that the butterflies should open. You can get an RPM activated switch and set it to whatever RPM you want, but why spend the extra cash when the circuits are already in place for you in the ecu.
That is..if you dont have a 97 galant like I did with no EGR from factory...but then again if your dohc..you ecu swapped.

sorry, there probably aren't any eproms for the galant ecu. i meant i used an eclipse 94 eprom.
there is also a way to use a hobs pressure activated switch to activate it at a set boost level.
i read the hobs setup off dsmtuners. but again it's set works at 3000 rpm. I guess i'm trying to figure out which way is the easiest and most effective way to utilize the cyclone intake. from what it sounds like I'm guessing the 4100 rpm, ecu chip is the way the way to go.
So i need to get an eprom ecu, get a chip to activate a fp selenoid at 4100 since that is the original jdm rpm activation for the second runner. I looked on dsm tuners, and they have the cyclone option to their chips you just have to specify it.
a hobbs switch setup wouldn't cause it to open at a certain rpm, it would cause it to open at a certain boost level. so you could set it to start opening at 9psi or so, so that it spools up fast, then opens up to give you good top end.
hey guys what intake did you get for the jdm 6bolt. I guess i'd have to treat it like a 1st gen. If i'm correct i'll still want to use the 7g=2g Mas sensor. I'm looking into the dejon's for this application, but just wanted advice before i buy the wrong one.

2g Mas has a higher flow capacity compared to the 1g...I believe 20% higher either or...it will work.
MAF Translator and a GM sensor =D thats whats going in the new project car. Ive heard good things.
Got the GM flowsensor...just need the maft .. but thats all at the bottom of my todo list

Ahhh...good suggestion Rob. 8) The new version even has a better control on Air/Fuel tuning too and not to mention being able to vent to the atomosphere w/o the worries of idling and spoolup!
you really need to tune your car to run right on a stock mas. then after that, install the maft. you can't just install the maft and expect to have a perfect map (or an identical one to stock) by just setting it to 0 for low mid and high. ask sabzi about that, i think he might have some useful feedback.
if you get a dsmchip he can calibrate it for whatever mas and injector combination to run and idle like stock. without fucked up low throttle fuel maps, and you';ll get around the same gas mileage as with standard injectors.
i have a 2nd gen mas with 550cc injectors, and with the chip, i get around 31 mpg on the highway(provided i keep the ecu in closed loop as much as possible, and lay off the boost) thats better than i had with my 2.4 dohc stock motor.
indeed, out of the box, the maft does not do a good job of imitating the stock mas at reading airflow. it needs to be dialed in properly, to simulate the stock sensor as best as possible. that said, it does allow for quicker spoolup, and can count more air than the stock setup.
as for a hard intake pipe, you will want one from a 2g as well. all aftermarket ones should be big enough for a 14b, but the 2g has the shape you need.
Aren't the 2G and 7G MAS the same??
yes they are the same.
Any one know a good place to get an EPROM Ecu. Been looking on ebay, but not too sure what to trust.
also found this
Think it's legit? they never responded to a question i asked them.
So long as someone has good feedback on ebay you're generally okay... or find someone on dsmtrader that's Paypal verified.
in doing the engine swap, do i need to get a new wire harness or will the one for the 4g64 work with the jdm 63t. That's the only reason i was contemplating getting the wire harness, but i missed it all together :roll:
i'll check out dsmtrader

you are going top need a harness so you can identify and cut the ecu plugs off. It will also make it easier for you since you can use the resistor pack conector, ignition transistor conector, coil pack connector, cam angle sensor conector, the connector for your boost control solenoid. and i don't know if i'm leaving anything out. that way you can have an easy, clean, and waterproof wiring setup, instead of a bunch of spade connectors. PLEASE make sure you solder and heatshrink every single wire before you wrap each connector group in electrical tape, then awiring loom, then electrical tape(just like factory) you want to ensure that you have no shorts now or ever, and that all electrical conections remain free of oxidation so as to maintain a healthy resistance level. It takes a little longer to do it right, but i'm alot more willing to show people whats under the hood since i kept it all clean)
what if i was able to get ahold of 1g ecu and wiring harness, then i could just plug everything in right. or 2g for that matter. Im trying to save time.

from another thread:
seriously the only way to do this is to create a hybrid harness.
you are going to want to identify and label every single wire at the ecu plugs for your galant harness. place your labels a few inches back from the connectors to give you room to work with, then cut off the ecu plugs. then do the same w/ the eclipse harness, but place the labels within a half inch of the ecu plugs, and cut the wires about 4 inches from the connector. Then using pinout diagrams for your stock galant ecu, and the eclipse ecu of your choice, match up every wire, solder and heatshrink every single one, one by one. but make sure you leave the eclipse labels on every wire.(you can get electrical wiring labels at the home depot) the reason you want to keep your stock harness, is because its already the right length and fits your car plus it has to not only plug into the ecu and engine properly, but it has to plug into your cruise control, and the body harness that has many vital things like your instrument cluster, and fuse box harness.

you are probably going to want to go with the 2nd gen ecu setup cause there are some compatability issues with the speedometer and wheel speed sensor. i think i may have them figured out, but its pretty complicated and would be easier to just go the other way.
I see it as if your car is OBD1 then go with a 1g ECU. OBDII, 2g ECU. For me being OBDII, the ECU swap was rather simple after I figured out what needed to be done. But I dont know how 94-96 ECUs are setup, so start looking at those diagrams :wink:
looking at what seth and the other guy posted on this thread,. It looks like the two ecu's are different from 94-96 to 97-98. and what i'm looking at is the plug's 94 has 3, 98 has 4. Where can i find diagrams to find the differences between 1g and 2g? i'guess i'd have better luck searching dsm sights for those. hehe :?
i guess i need a print out of every pin and what it does...
{As we check back with our hero}
Look what i just found momentsd after i posted the other.
found this sight with this pdf file, if you go down to mitsubishi eclipse 2nd gen
http://www.plxdevices.com/ecudatabase.htm
compared too...
http://www.iamsethmo.com/Manuals/ecu...harness-2G.gif
the Galant 4pin is teh same setup at 2g turbo ECUs. My 4pin connectors plugged directly into the 2g ECU. I just had to change a few wires around and add a few wires.
As for the OBDI galants and 1g ECUs, Im not sure how those work, maybe mr John or Sabzi can tell you https://www.thegalantcenter.org/styl...ult/tongue.gif
when i looked at the 1g diagram it didn't even come close to matching up with with the 94 ecu. no where near to close. This is probably the only time i wish i had a 97, 98. Went to the junk yard today, all they had were 1g's but all the ecu's were gone, none were turbo thou, most were sohc. found one 1g dohc n/t. thought about it, but figured i probably couldn't use it.
One junk yard had a 95 turbo ecu prt # MD 309947. any way to tell if it is eprom by the numbers only. just got off the phone with the local mitsubishi dealer parts guy. he said it's for gst.
were most 95 models eprom or just gsx?

all 95 eclipse turbo ecu's were eprom, no matter what the part number
but just to be sure that their ecu wasn't replaced, there should be an e somewhere by itself on the part label and also usually right after the last 3 digits on the side.
look on ebay too if the price isn't right at the yard.
and since its an eprom, it doesn't matter if its california, automatic, awd or front wheel drive, cause you can have the chip made to whatever your setup is.
nice!! they wanted 175, so i'm going to get it tomorrow. I think i read on vfaq the e was on the top, not the side, and if it has a m, or another letter it's not.
Replacing the chip will also remove the speed limiter?
now i just need an engine harness, to make it easier, anyone have a 2g or 97,98 harness they will part with :wink: https://www.thegalantcenter.org/styl...lt/biggrin.gif

ask the yard if they have one of those too. and yes they can remove the speed limiter if you please
these guys are diks actually. They act like they don't want to help me. or i don't have the money to buy... good ole' missouri :evil: but i asked them, they said they didn't have the engine harness. i really think that since it's hot as hell they don't want to go out in the heat. I can see about 3-4 2g's from the entrance. and i know the g their pulling that ecu out of has the wire harness.
bass tards :doubleup: :321:
If you are going with a 2g ECU, theres no need for a 2g harness...
i have a 94, galant... three plug ecu. :roll:
I have a set of the 4 2g style plugs if you want them. Came with my ECU. I can even give you some extra pins that you may need. PM me with your addy and Ill ship it tomorrow
those will help, but you are still going to need all the conectors for your coil packs, resistor, jdm galant vr4 cam angle sensor, and transistor pack.

:roll:
as complcated or complex as it seems, its actually a fairly easy swap. just a lot of parts to hoarde.
but once you have them, it's all downhill
ok... so say i get 2g ecu and wire harness. what will i need then. the harness should cover the coil packs, right? but what about the resistor cam angle sensor and transistor pack. I would think all those are on usdm gst, but would they be included in the wire harness
