hold on now, if this is v1.3
here is the manual

[ratatack]

thanks but its a version 1.7

I would try the stock MAS to at least rule out the translator/GM MAF being bad. If that doesn't work right, then you know you have an issue that's probably in the wiring or a plug not seated properly or something.

 

[eclipse-gs-t]

ok in the first pic you see where it says
MODE all four have to be off
ok now you do have 560cc right so AUX has to be on 0 and the base to 4 ok
then the other dials have to be done with the datalogger

well ther is only two versions 1.3 and 2.0 anyways if you want the 2.0 you can upgrade it here

for only $30

ok in the first pic you see where it says MODE all four have to be off

Dip switch #3 is enable startup enrichment if turned on, so I don't think this would have a huge impact on idling.

ok now you do have 560cc right so AUX has to be on 0 and the base to 4 ok

Yep, that would work if she had a 1g and 470cc injectors.

yeah im going to go with that i think the dials coulda been set wrong bc no one i know including myself knows anything about this box im going to have my friends who are helping me with this problem read this forum and understand it and maybe we can get some where ill keep you guys updated and ill post more pics if need be hopefully this should get us some where and i can get my car running

she has to do version1
it is way different then v2 look at the manual i sent

 

[JMiller]

Do a boost leak test, and when you say idling bad could you go into detail, how exactly is it idling.

 

[ratatack]

like you have to revl it up to keep it going ill see if my friend can get a video of it tonight and post if not ill do it over the weekend bc id like to have this addressed i dont really want to trade it off it has a ability to be a nice and fun lil car

 

[JMiller]

Have you done a BOOST LEAK TEST yet, if not i would do that first.

 

[ratatack]

[FONT="Fixedsys"]i know I sound really dumb when i say no but i dont believe we have i could be wrong im going to find out tonight if thats what drew and steven has done bc we are stummped at this and the both of them have a understanding of this car mainly drewbie he has a na eclipsed now turboed he says its almost the same my 4g63 engine is his backwards? [/FONT]

 

[JMiller]

Ok, i would suggest checking the alternator and battery also if the stuff you do with the translator/MAF does't work.

I just looked into this more and I bet she's reading the circuit board revision number, which is different than the unit's version number. If you look in the version 2.xx manual, you'll see the picture in there has a board with revision 1.6 which is even earlier than her 1.7. I verified this with my MAFT, which is a v2.02 I believe. Here is a picture of the whole thing and then the board revision number.

well on this web
there is only two manuals v1 and v2 which does she needs to use?

 

[snowborder714]

I would say the v2.xx manual. The only way to be positive would be to look at the sticker that should be on the top (which doesn't appear to be there). That'll have the version number on it.

But by the board number, the looks of it, and the current settings, I'd say it's a v2 unit. I can't say I've ever heard of someone with a v1.3 unit.

i had one but i upgraded just buying the chip

 

[ratatack]

mine says rev 1.7 on the bottem right

 

[ratatack]

Im Am I Guess Now That I Think Of It Reading The Revision Number How Do I Correctly Find The Type Of Version It Is

 

[eclipse-gs-t]

http://www.fullthrottletech.com well what about if you give them a call a make sure they tell you which manual version you should use, this is very important.

 

[snowborder714]

Why not try some other ideas out before really worrying about the MAF-T? Or just try the settings from both and see if one really doesn't work or one works better than the other?

 

[ratatack]

i was thnking of that but scared it would hurt the car in some crazy way but its worth a shot

 

[snowborder714]

I forgot to plug in my GM MAF after pulling the engine recently, and when I started it up it ran like crap. Sputtering, extremely rich at idle, the whole deal. So something has got to work, whether it be running of the stock 2g MAS or an issue with the GM MAF or translator.

I'm assuming you have gone through all the plugs to make sure everything that is needed is plugged in??

No offense, but it sounds like you're at the point where you (or your two friends) need to start poking around in there and checking stuff out and trying things. Find something you don't know about and post up. Go through all electrical connections. If you're unsure about what a certain plug is that's just dangling somewhere, look in this tech article. If you're still not sure if it should be plugged in, ask. Once you start helping us with new info, we can start giving you more things to try.

Make sure all vacuum lines have a home. If you find ones that are unplugged, post up and ask if they can be left unplugged or if they need a home.

Have you done a boost leak test yet?


And do you happen to know why your adjustable cam gears are not set at zero? If they weren't set on a dyno or by degreeing them while the engine is on a stand, then they weren't set correctly and I would suggest moving them back to zero.

just wonder did you or your friends try anything we told you or not yet, just in order for us to have any other ideas

This is her friend... No offense taken man... heh. This is my first time messing with a 2nd gen factory turbo'd DSM... I've owned an eclipse before, but it was (should I dare mention) a 2000 GT and I ended up selling it and buying an ATP turbo upgrade kit for my 95 2.4L neon. Thanks a bunch for posting that link. It's helped in figuring out exactly what and where everything is suppose to go. I actually found that the speed sensor plug wasn't plugged into the sensor... because it was GONE! That's a problem for a later date.

This car was purchased from a guy up north who had pre-modded it which really sucks when trying to diagnose problems like this. Not to mention the work quality and craftsmanship we're purely jerry-rigged. I say if you're gonna do something, do it right the first time. Now, on to the car......

(Although not directly related to this thread, I said speed "control" sensor when I meant "speed sensor"...)

Make sure all vacuum lines have a home. If you find ones that are unplugged, post up and ask if they can be left unplugged or if they need a home.

That's one thing I'm lost at... this thing has a ton of vacuum ports on all sorts of sensors, which I'm not sure are even needed. You will find photos of all of the sensors that have vacuum ports on them that lead nowhere. Please advise which ones can be unplugged (if any) and also if they need vacuum hoses plugged in, to where they're suppose to be routed.

Hard to make out, but the white vacuum port that is under the battery.

On that 2gen connector thread, there is an Engine Speed Detection Connector. I searched and finally found it taped up with electrical tape... it looks like this.... Is it not suppose to be plugged in?

This is something else I found while I was checking all of the sensors...
CAM SENSOR
This can't be good. Although the connection is not broken, the plastic part of the sensor itself is. May be a problem, if not down the road.

Have you done a boost leak test yet?

Unfortunately I have not. I have yet to buy the supplies to make one. I will eventually need to make one for both turbo cars.

And do you happen to know why your adjustable cam gears are not set at zero? If they weren't set on a dyno or by degreeing them while the engine is on a stand, then they weren't set correctly and I would suggest moving them back to zero.

The adjustable cam gears were pre adjusted before the car was bought, I knew nothing about them so didn't want to mess with them. They were not adjusted when new engine went in. The previous owner had set both intake and exhaust gears to 10 degrees advanced (which is 5 hash marks on each gear.) I didn't want to touch them because they are supposedly custom ground cams....

THANKS for the help guys. Hopefully these pictures can help us as we're running out of options and soon I'm gonna burn the car (kidding!!)

peace out,
S


eclipse-gs-t, you may want to take off-topic to PM... not sure how strict the mods are on forum rules... just a suggestion
