Help with Tuning DSM (Eclipse GSX)
 

Ok I know its a longshot but I trust a lot of yalls input. My friend has a gsx eclipse that is having serious running issues. Im trying to find someone to help us out that is familiar with the 4g and dsmlink. Long story short he spent a lot of money getting it "tuned" at a shop that turned out to be basically thieves. They gave him a dyno printout that shows the car did great (298hp and 320ishtq) he paid the outrageous bill but around halfway home it ran like garbage. Calls them back the next day, and they shut shop. Just straight disappeared.

Anyway the point is does anyone have a dsm, or know a friend with a tuned dsm that has a recommended tuner or can help guide me through dsm link. We are working out the mechanical quirks atm such as exhausts leaks and a couple minor things but there is something else going on I feel with the tune but I only know about halfway what im looking at.

I knew one guy that lived in middle TN and had an 800 hp talon he built and tuned himself but Im not sure hes in the game anymore.

Yes. What software are y’all using?

its a 4g63. you put an MBC on it, turn that way the fuck up. and send it

dsmlink but I cant remember what version atm ill have to ask him to see. Also could be called ecmlink.

no

yes

Is there a way you could find out?

You know better than that :r:

course. im only joking

Alissa might be able to help because they may do them at msp.

Ok had him check and its dsmlink v3. Specifically v3.29.64

Yes Kendall does. He has an eclipse. But he uses hp tuners

Matt Lincicome? Something like that I think

Should we source a hp tuners?

Hptuners lists the vehicles they support on their website and mitsubishis arent on there.

So how does Kendall use it for tuning them?

Insider tip: he doesnt

Ya I was wrong. It’s ecmlink

Geez. Relax

Ok cool. is that version we have ok or should it be something different

Alot of unnecessary bs posted here fella's...

I own a DSM! What year is his car and its mods from stock?
It is very possible the shop done a decent job and something when wrong on the ride home.

Its a 95 with a 6bolt swap. I believe 1100 cc injectors(ill check) and ill have to check to see what turbo he has. The shop just shut down and disappeared, his isn't the only one that has had problems after going to them. He had a running issue after driving on the highway for a while before taking it over there, they claimed to fix it (I figured that part out in the tunes settings and fixed it) but since he got it back it wont boost over 10psi if you go wot and wont go over like 4.5k rpm. That was on the ride home, before he took it to them it ran decent at the po 19psi tune. We still have some exhaust leaks and a couple wiring issues to fix that they were supposed to take care of but didn't.

Ill update with as full of spec sheet as i can get when i can. Could you give me steps/pics on how to save the tune file so i am able to share it if need be?

Ill to go back and check on the tune saving its been a long time since i had my 95 tsi, the gst i currently own is a 98 an uses a black box ecu that is different.
These cars are very bad for boost leaks and with the 2 symptons you just described actually makes it sound like your issue. I would leak test it first.
Is it still a maf car or changed to map based?

We tested it before and found the throttle body leaked and fixed that. Didn't find anything else but next time we get it to my work ill check it over again better. Had to rush last time so I may have missed something. Its still a suck through maf setup. Thought about going speed density but im not sure which way is best.
