Josh '88 Posted March 22, 2006 Report Share Posted March 22, 2006 After installing a wideband O2 setup on my Quest, I noticed that I was running terribly rich with a stock, unhacked 1G MAS. In order to fix the problem, I had several options: -Try to hack the 1G MAS, hoping that it would run properly while idling, crusing, and at full throttle-Install a S-AFC (Secondary air/fuel converter) that allows me to adjust my fuel settings -Install a MAF Translator designed for a 1G DSM, but is also a plug-n-play setup for the '87-'89 Starquests Of course, I went with the Translator setup. Not only does it allow me to adjust the fuel settings like the S-AFC, it is also a cheaper setup & extremely easy to install/tune. Here's a picture of parts needed for the conversion: http://www.26liter.us/gallery/albums/userpics/10048/100_5877.JPG -1G MAF Translator (paid $207 shipped via Ebay)-3" General Motors MAF (paid $45 shipped via Ebay)-3" universal air filter that's washable/resuable (paid $15 shipped via Ebay) You are able to use 2 different GM MAF's with the Translator; a 3" MAF or a 3.5" MAF. I used a 3" MAF because it was easier/cheaper for me to find. Once you have removed the OEM/1G MAS from the car, install the parts in this order: air filter--GM MAF--stock accordian hose--turbo Since I had an accordian hardpipe on my car, I installed the parts in this order: air filter--GM MAF--silicone hose coupler--accordian hardpipe--silicone hose coupler--turbo Your setup should now look like this: http://www.26liter.us/gallery/albums/userpics/10048/100_6193.JPG Now, you're ready to install the Translator. The Translator has 2 connectors, a white wire, and a purple wire. The white wire & purple wire is only used on the 1G DSM's, so I just coiled them up & zip-tied them out of the way on my Quest. 1 connector plugs into the General Motors MAF, like this: http://www.26liter.us/gallery/albums/userpics/10048/100_6156.JPG The other connector plugs into the car's MAS plug. I had to trim the Translator connector in order for it to fit. Here's a pic of them plugged up: http://www.26liter.us/gallery/albums/userpics/10048/100_6157.JPG The installation is now complete, and you should have something like this: http://www.26liter.us/gallery/albums/userpics/10048/100_5884.JPG I mounted my Translator box with velcro, so it's easily removable if needed. Before you start the car for the 1st time with this new setup, you need to remove the Translator's top cover (4 screws) and make some "initial adjustments". The Translator instruction manual will tell you what to do. Since I was running a 3" MAF, I didn't have to make any adjustments. I started up the car, and it idled perfectly. When I took the 1st test drive, I was running rich at mid-throttle & full throttle. I turned the car off, made my adjustments, and took another test drive. My mid-throttle was set perfectly, but full throttle was still too rich. After the 2nd adjustment, Everything was set perfectly. WHEN YOU MAKE ADJUSTMENTS TO THE TRANSLATOR, THE CAR MUST BE TURNED OFF! For the record, my final settings are: http://www.26liter.us/gallery/albums/userpics/10048/translator.JPG AUX=0BASE=0IDLE=0 MID-THROTTLE=1 turn counter-clockwise (5% lean)FULL-THROTTLE=3 turns counter-clockwise (15% lean) On my wideband, my a/f ratios are: idle=around 13 to 1 (engine fully warm)mid throttle=around 11.5 to 1full throttle=around 11.5 to 1 Link to comment Share on other sites More sharing options...

Josh '88 Posted March 22, 2006 Author Report Share Posted March 22, 2006 Wow...was it really that easy?!! Great job Josh, your car should run even better now. It took me less than an hour to do everything, including the 2 test drives & final adjustments. I spent the most time trimming the Translator plug to fit the car's MAS plug. The Translator helped me to achieve my car's full potential. It runs stronger now under full throttle, because it's not being flooded with too much fuel. I can't wait to dyno it again. I want to go to the local dragstrip really bad, but their first Test-n-Tune night is April 1. Link to comment Share on other sites More sharing options...

Couth'nize Posted March 25, 2006 Report Share Posted March 25, 2006 I beleive that's the 2005 schedule. This year, Friday is on the 31'st of March.Yeah, a mini meet would be great. Link to comment Share on other sites More sharing options...
Coke Posted March 28, 2006 Report Share Posted March 28, 2006 You suggest that the GM MAF increases the amount of airflow that the engine can breathe in? The stock MAS/1g MAS has only a small opening, where air can be breathed in through, whereas the GM MAF has a wide open 3 inch hole. I'm going to be going this route shortly, and I am very glad to see that it worked out well for you. Link to comment Share on other sites More sharing options...
Technology Posted April 9, 2006 Report Share Posted April 9, 2006 yeah, the ease of installation is unparalleled. I would do it again if i didn't have 90% of the stuff i needed for mpi! Link to comment Share on other sites More sharing options...
emagdnim Posted April 9, 2006 Report Share Posted April 9, 2006 You should run a blow-thru set-up and put the GM maft in the UICP. That way you can just run a filter on the turbo. Link to comment Share on other sites More sharing options...

Coke Posted April 10, 2006 Report Share Posted April 10, 2006 Does it matter if I put the GM MAF between the TB and BOV, or BOV and Turbo?? What about Before or After the Intercooler? I'm a little confused on where exactly is the best place for this thing. I <3 Josh's Car Link to comment Share on other sites More sharing options...
GoFastBeater Posted April 10, 2006 Report Share Posted April 10, 2006 between the bov and t/b would be best. that way it's not dumping metered air. Link to comment Share on other sites More sharing options...
notfried Posted April 30, 2006 Report Share Posted April 30, 2006 can we use this without the wideband?and just use the autometer a/f gauge? thanks,Russ Link to comment Share on other sites More sharing options...
Technology Posted April 30, 2006 Report Share Posted April 30, 2006 yeah, that's how I ran mine when i was using it. kinda wish I hadn't sold it, but If I hadn't, i wouldn't have a 274 cam Link to comment Share on other sites More sharing options...
tshajlij Posted May 6, 2006 Report Share Posted May 6, 2006 Can I still do this if I have an 86? You mentioned that it's plug in play for the 87-89. I know the 86's have slightly different ECUs. Would I need to rewire everything to install the GM or 1G DSM MAF? Link to comment Share on other sites More sharing options...
Truth Posted May 6, 2006 Report Share Posted May 6, 2006 you can use this without the wideband, but it'll be hit and miss with the tuning of it. since the wideband gives you exact a/f ratios, it would be a lot easier to use the translator.

tshajlij Posted May 8, 2006 Report Share Posted May 8, 2006 Well, I'm actually currently looking into installing the 1g DSM MAF or GM MAF and was first wondering if this required rewiring my ECU. Then I may try to get my SAFC II working in my car (it doesn't run well with the stock MAF right now). If unsuccessful with the SAFC, I'll want to try the fuel tuning system above. Ultimately, I'll be getting a wide band too...no doubt about that. Link to comment Share on other sites More sharing options...
Truth Posted May 8, 2006 Report Share Posted May 8, 2006 there is no ECU rewiring required for running the 1G or the MAF-T. Link to comment Share on other sites More sharing options...
Bad2Rass Posted May 9, 2006 Report Share Posted May 9, 2006 Hey Josh hate to steal your thread but, here are pics of mine I went over to Jon's and we thought it would be a good idea to do things like this. I am better than all the rest I have the factory mas and the GM mas I am double MASing it. 8) http://i45.photobucket.com/albums/f65/bad2rass/IMG_1017.jpg http://i45.photobucket.com/albums/f65/bad2rass/IMG_1016.jpg Actually the reason why we ended up having to use the factory mas lid, it is only the lid, was because I ordered the wrong size filter I thought it was a 3 inch MAS but its actually the 3.5 in so this was the only way i could get it to work till I order the right filter. But it runs great we raised the boost to 15 PSI and at full throttle it runs about 10.5-10.9:1 Idle about 13.0:1. I think this is the best thing since sliced bread.

exgmguy Posted May 9, 2006 Report Share Posted May 9, 2006 It is kinda weird how these cars like to idle so damn rich. Mine idles like crap any leaner than 13ish to 1. Link to comment Share on other sites More sharing options...
jerrold carter Posted May 13, 2006 Report Share Posted May 13, 2006 Iagree with you this thing is awesome alot of guys are going to knock it because they have already purchased MPI parts. Don't get me wrong the MPI guys are way ahead as far as all out HP, but this thing is easy enough for and old guy like me to tune.Car runs way strong.

Fuze Posted May 19, 2006 Report Share Posted May 19, 2006 I wonder how much of a range of tuning you can get with this, guys running big turbos on non MPI cars can probably run dual secondary injectors and lean it out on the low end of the rev band. That way you've got more fuel capacity up top with some healthy boost, if you're finding the limits of the primary/secondary setup.. Link to comment Share on other sites More sharing options...
88_TSi Posted May 28, 2006 Report Share Posted May 28, 2006 WOW! I just installed my MAFT (2.02) and tuned it with the new wideband. I cannot believe how much better the car runs with this set-up rather than the 1G MAS I had in there berfore.... I was running UBER-rich ALL THE TIME according to the wideband. It took me about 20 minutes to install the MAFT and get the wiring just like I wanted it (Luckily, I had already switched my plug to a 1G plug back when I put the 1G MAS on - so that quickened the job today). Also, with the MAFT, it seems the readings on the wideband are ALOT steadier than they were with the 1G MAS. All in all, I'd have to say that buying this Innovate Wideband / MAF Translator / 3" GM MAF was one of the best mods I've done so far. And Thanks to Josh for an informative post with nice pic.s! That definately came in handy. :wink: Link to comment Share on other sites More sharing options...
1st_gen_eclipse_89 Posted June 9, 2006 Report Share Posted June 9, 2006 does anyone know where i can find the wiring diagram for a stock mas air to a 1G mas air? i just got one of these translaters and a 3 inch gm mas air unit, but i still have the stock air can and mas air on my quest. need some direction on how to wire it up. :-k Link to comment Share on other sites More sharing options...
