So Im looking to run Dsmlink on my eclipse to account for the fmic exhaust 16g and bigger injectors. I am looking to purchase it from extreme psi and Im a little confused. After much debate I have decided that im going to run a 3 inch gm maf as well. This is where my conflict comes to play. When purchasing DSMlink it gives you the option for what maf you are running either a gm maf with translator or just a maf straight to the ecu. It also gives you and option for a gm maf cable. Does this mean I can run a gm maf straight to the ecu and let the dsmlink run the maf? Also the gm maf cable they have an option for would that be the cable to connect straight to the ecu? I know Im going to get that I could get on ecmlink and ask them but I tried and it wont let me register therefore I was hoping someone on here had some first hand knowledge that might be able to help thanks in advance.

Sounds like from Here you can connect it directly to the ecu. "I'll walk through a sample calibration of my own car below. This is a 1995 AWD Talon with 850 injectors running E85 and a GM 3” MAF connected to the ECU."

From the DSMLINK site HERE
GM MAF and MAFT: When selecting MAF Type below, please be aware of the difference between running a GM MAF straight to the ECU using our GM MAF cable vs. running a GM MAF through a MAF translator. If you're running a MAF translator, you should select the option below specifically for GM with MAFT.

If you plan to run the GM MAF straight to the ECU without a MAFT, then you will also need one of our GM MAF cables. This can be added below as an order option if you need it.

sounds great thanks so now I am wondering if I should just go to the ecu or go ahead and get a translator

I would go without the translator. If you have Link, you'll never tune with the translator. It's just something else that can break.

if the DSMLINK is anything like the tuner I'm using, there should be a section to enter the transfer function for your GM MAF, so you won't need the translator (assuming the voltages and such are the same, which is sounds like). The DSMLINK should just adjust the ECU accordingly.

They had to do something a little more fancy since a Mitsu MAF outputs in a variable frequency signal rather than a variable voltage signal. The translator will translate the voltage of the GM MAF to a frequency output that the Mitsu ECU can use. I imagine w/o the translator they have the GM MAF hook into another unused variable voltage input on the ECU and transfer to the fuel map from there.

I used a translator myself because I already had one and at the time they didn't have the ability to hook the GM MAF directly to the ECU. Now that you can do that, I wouldn't bother spending the extra money on a translator.

I am looking into getting the gen 2 translator that from what I here tunes itself once u put in the a/f ratio u want as long as u have it hooked into your wideband so I think Im gonna try this approach and then use link as well any opinions?

Does Link work with the GEN2 translator?

Seems like you're over complicating it to me. You'll have to use 2 different tuning systems. Maybe just get the GEN2 first and see if it can tune it enough where you don't need link.

well since im going to be installing this setup for jdmcivic (shaun) I think maybe we should just go with the link and gm maf.... or like chris said just the gen 2 for now since we are not running e85 yet...

The only problem I see with running just dsmlink is
1. I want to run a better non vented blow off valve and no not just for the sound because even the crushed one thats on there now is leaking
2. I want to run a gm maf bc the stock maf and intake is leaking like hell and also is restrictive as shit.
That being said if someone can tell me how I can run a gm maf and a vented blowoff valve without having the translator that will solve my problem. Like stated before I think theres a way to hook the gm maf into the dsm link without a translator but I have no idea how to do this. As far as the question of can you even run link with a version 2 translator I dont see why not as it would still be doing the same function as the gen 1 only its setting all the settings for you.
Any ideas on this?

Ok so I am going to order dsmlink with the option of a gm maf straight to the ecu and then buy the cable as well. I hope that this will work and I wont end up ordering the translator down the road.

You may already know this, but if you want to vent to the atmosphere mount the GM MAF behind the BOV. If you mount it in front of the BOV without a recirc tube you will be venting metered air into the atmosphere leading to an incorrect airflow reading and an incorrect amound of fuel being injected. The only caveat with mounting here is it will be a blow through setup so you will need strong band clamps and good quality couplers to deal with the pressure.

What Nate said. Otherwise if you're using a Bypass valve, you can mount either after the BV (blow through) or before the turbo/recirc return.

ok so now I am a little confused on this wouldnt I want to have the bov mounted before the maf? because If I mount the bov after the maf then the maf is going to be reading air amounts that are possibly going to get vented. therefore giving a rich condition maybe I am missing something.

Yes you are correct. it should be air filter -> turbo -> BoV -> MAF -> TB. I think his wording was just a little confusing, but that's what he meant.

If you are using a bypass valve (recirculating) then you have some more options, but it doesn't really matter.

Not sure how much more direct I could be...

Like THIS

behind can mean before or after (just had to give ya a hard time)

How's the new house treatin ya Nate?



BTT Yes that looks correct.

Guess I was talking in terms of air flow direction. I get what you're saying though.

House is great. Haven't had much free time to put together a get-together yet. Probably wait til Spring and have a cook out.
