Well I decided to not go the safc route and instead im looking into the dsmlink...But I'm confused about it...I was hoping you guys in the mitsu tech could clarify some things im not sure of.

Well I know you need a 95 ecu in order for me to get it installed due to the fact i have a 97 gst...But what is the eprom? is that a seperate chip i would have to get and then install it on the ecu? or is the erpom built into all 95 ecu's?

from there i remember rob telling me i would have to change the firing order on my car...Juan told me i should get a labtop which i now own...

I went to what was said was the official dsmlink homepage but it looked rather "flakey"...i dont know if this website is the kind i would give me debit card info out too...im kinda paranoid...but maybe u cant judge a book by its cover?

So is there anything else from there i would have to do? or is that it? Is dsmlink "better" than a going the safc route??? Im still learning and trying to soak up as much info as i can...thanks in advance

 

The deal is almost all 95 ecu's are eprom so they have to be socketed inorder to instal there eprom which is what you program to control your cars engine. DSMlink is very safe and prolly the BEST way for you to tune your car, it will make you toss that stupid SAFC out the window in a heartbeat. The firing order thing is very simple 95-96 cars dont have the same firing order as 97-99 cars thats all...

 

can a dsm link be used on a non gst ? such as my 420 turbo? its a 96

 

No.

 

Make sure the 95 ecu is a eprom.
You then need to get it socketed.
Thats not big deal. I will tell you how to get that done when you get one. There is a good chance that the ecu you find will already be socketed.
The dsm link is a small board that plugs into the eprom socket. Then you plug the supplied cable into your diagnostic port and connect via laptop and tune. I can help you tune it also. It is a great tunning tool.

 

jw but why did you go from DSM link to AEM I mean I would think AEM is way better but what is the DSM link missing as in tuning options?

 

Thanks tom, i'll hold up to that when i get it...i noticed john(ls1fever) has a 95 ecu for sale...so i'll probably scoop that up from him...another question i had is does it matter if the 95 ecu u have came from a manual or auto? and how do u know if the ecu ur buying is for manual or auto???

is that dsmlink (official, but doesnt look official) website the only place i can order dsmlink through?

would i still need maf tanslator if i go dsmlink while venting my bov (i have a greddy type rs bov btw), or does that not matter?

 

It doesnt matter if its a manual or auto ecu in a 2g. The tranny is controlled by a tcu and both auto and m/t use the same turbo and injectors. On a 1g they dont so there is a difference in the ecu.
They are working on making it so you dont need a translator to use a gm maf with dsm link right now. Not sure when that will be ready though.
If you use the stock mas you will still have the same symptoms when venting to the atmosphere.
There are some vendors that also sell dsm link but I would just order it strait from Tom Dorris off the web site.

 

DSM link is great for most people out there.
But you are still working around a factory ecu.
With as stand alone you are not working around any thing. It does only what you tell it to and doesnt think for it self.
It is not for the faint of heart though.

 

btw, you have to switch the plug wires around b/c the firing order in a '95 GST is different than the firing order in a '97 GST.

IMHO:
SAFC = tricking your ECU into thinking certain things are true (that actually aren't true), such as changing airflow values to compensate for bigger injectors, in order to get the desired result, such as a certain A/F ratio.

DSMLink = ability to modify your ECU from the stock fuel maps on a global and sliding scale such that in WOT mode, your car achieves a certain A/F ratio. The good point is that you aren't "tricking" your ECU like w/ a SAFC.

AEM = ability to throw the stock ECU maps out the window and pretend that you are a mechanical engineer for a day.

Depending on how much money, tuning knowledge, and time you have, you may want to move up or down this scale.
