| Post subject: | DSM/GM MAF Translator from Ramchargers |
Well, I purchased this item during the first couple days that it was available from remchargers. The cost was $207 shipped, plus I bought a brand new 3" MAF for $98 from GM parts direct. You can, of course, buy a used one from a junkyard for $30 or so I would imagine. Anyways, I just chose to buy a brand new one. In terms of choosing the 3" over the 3.5" MAF, I just don't see a need for the 3.5" I doubt it would have provided any benefit, after all, I'm just running a little 16G. Save the 3.5" for a bigger turbo that has a big compressor inlet. So, I installed it pretty quickly, the most difficult part was tapping into the RPM wire on the CAS to get a signal. I just took the CAS off completely and soldered it in (I only trust solder connections). I then hooked everything up, very simple, plug into original MAS plug, then plug other part into the new GM MAF. I just used the stock 1G intake tube, put the MAF in, tightened it down, and got a cone air filter to fit the other end. (Be careful! make sure and take the MAF with you to the store when you buy the filter to be SURE it fits. The MAF is, overall, a very weird size like 3.25", most all of the filters I tried didn't fit). Anyway, So I get everything in, reset the ECU and set the base knob according to the instructions and my injector size. Start the car up, and one of the lights (the "mid" light) is on that isn't suppoused to be. I call up Ramchargers and tell them. He asks me for the version number written on the cover. I tell him I have version 1.0. So, he says they'll send me the update that gets rid of the light issue, but that I can use the translator without worry. So...I take the car for a drive and immediately notice that the car feels different in normal driving, altogether smoother. I couldn't put my finger on it, maybe it was a smoother transition into engine braking. However, I also notice a horrible problem with slow throttle response. I would assume it can be tuned out, but I couldn't get rid of it. I think most of the battle is just driving your car, since you ought to reset the ecu each time you adjust the MAFT, and it takes the ecu quite a few miles to adjust. This was half my problem @ throttle tip-in. Since it would get a little bit better as I would drive, I could tell the ECU was learning, but the problem never went away completely. If nothing else, the translator gets rid of fuel cut of it's a problem and lets the motor breathe easier sinceour stock MAS is so crappy in terms of CFM flow. If you're into the rice-effect, then this makes the turbo/intake noise louder. I should also add that my best 1/4 time was with the 1G MAS, and not with the Translator. I'm pretty sure it was my fault, I hadn't really figured out how to tune it yet. Now, I have finished welding up a beautiful new upper IC pipe to mount it as a blow-through to see what that does for me (besides venting the blowoff valve to atm w/o running rich), but need to tune it if I ever get a chance to go home and play with the car. So, when I get to go home during thanksgiving, I'll put in the new updated version of the chip that Ramchargers sent me a good while back, and pull out the laptop, make a few runs see how it does. I also should post some pictures then, cause the new setup I made is really really pretty. |

i was going to go with the dsm translator too but i think you just scared me! although i was going to use the dsm translator(blow through setup) in conjuction with an afc2. i hope tuning is your problem. i was really looking forward to this setup. i also read that to use the afc you have to set the knobs all to zero? if anybody can verify this i would appreciate it. thanks |

If you're buying the translator you don't need an AFC. |

Another quick question. Isnt' it true that with a GM maf, you can just put the maf sensor directly in front of the throttle body? why even bother with putting it in front of the turbo? Then you can put a filter directly on the turbo, or even just a screen on the turbo for those track racers... |

i want to run the afc with the translator so i have more room for tuning. |

I'd want that AFC, too. You could enlean the mix when at part throttle below torque maximum to increase power by 2-3% and increase mileage by 3-4%. AndyR, putting the MAF just infront of the TB would mean we could keep our loud atmosphere-vented BOVs and never worry about over rich mixture & turbo lag.  Damn, this is a great idea! Man I think I'll put a MAF translator & SAFC on my 4G15!! Edit: I accidentaly wrote you'll decrease mileage, so I corrected it. |

Yep, thats what I mean when I say "blow through". Draw through is putting it before the turbo.

Then you can put a filter directly on the turbo, or even just a screen on the turbo for those track racers... Quote: i want to run the afc with the translator so i have more room for tuning.
Like I said, an AFC is totally unnecesarry with the translator. If you wanted to waste $300 of your money so you could tune in between the already small increments of the translator and see virtually no gain , then go for it.Quote: I'd want that AFC, too. You could enlean the mix when at part throttle below torque maximum to increase power by 2-3% and increase mileage by 3-4%.
That is exactly the function of the "mid" knob on the translator, it controls %rich/lean from 1-8 PSI, and then I believe it transitions into the WOT setting from 8+ PSI. Hence all of the praise about a properly set up translator being able to dramatically reduse spool time (among other reasons).

I wanna know in how far the translator is tunable. Does it have the same possibilities as the SAFC, i.e. enleaning at 40% throttle up to 4000 revs, lambda=1.1/AFR=16.2:1?Would mean saving 300-450 bux.

I would like to say that I will be going to the translator setup in the spring. I already got the GM Air mass sensor from the junkyard for 20.00. Since I already have the SuperAFC and will be keeping it under avdisement of the DSM gang. Yes the translator can run on its own with whatever injectors you set it up for, BUT you can fine tune it for your needs using the Super AFC. So far the Translator setup looks very reliable from what I have seen on Eclipses running around. Yes I also agree just infront of the TB is more desirable and much more accurate. I have seen Super AFCs going for used $150.00 to 175.00, and New in the box online for $275.00. So if you chose to go spend $300-400.00 from the store thats your choice. I bought mine used, $175.00, and have had no problems from it. |

Update: Ok, I finally got home, had to charge up the battery, and vacuum off about 10 pounds of leaves and crap since the car has been sitting for 3 months. Did an intake leak test and needed to weld an extra bead on a couple of pipes. Got eveything together leak free. Finally put the updated chip in the translator and set the knobs for my injectors. I slapped the stock 1G intake back on with the screw and plug holes weded shut since I didn't have time to make an intake, I had to get back to school. The battery finished charging and I started it up, ran like sh!t, barely idles, and I gotta keep my foot on the gas to keep it idling. Oh well, threw all my crap in the car, slapped plates on it and left. I roll on the highway for 4 hours/ 260 miles, come off and the car is a bit better, the ECU did it's job and learned something. Just as claimed, with the BOV vented, I can tach it up, vent and it doesn't bog/ run rich, the throttle tip in problem seems to have subsided, I knew this when I came off the highway after 4 hours and over-reved like mad on my heel-toe d/s. Hooked up the laptop and took some logs, everything looked fine, I wouldn't spend a cent on an AFC, nothing in my TMO logs tells me anything should be changed, no need for anything else. Oh, and the MAFT adjusts in 5% increments in 4 areas and one AUX trigger. You could ask me 50 million questions about the translator and it's adjustment capabilities, and if its inprecise enough that an AFC is really beneficial. I dunno, call up ramchargers and ask them. Anyways, I snapped a couple pics before I put the intake back on:   Oh, and I gotta show off my interior while I'm posting pics:

THIS is what I wanted to hear! Seems like there is no need for an AFC. 5% is exellent! What's with that AUX trigger? Could this be used to enrich/enlean? If so, an AFC would only be needed in rare cases.

Where did you get the silicone tubing for the MAF? What size are they? I got the dejon tool pipe and the pieces supplied are to short and keep on blowing off (I ended up welding an extra bead on the MAF but still need longer hoses) |
