I got my used D1SC with a pro-m mass air sensor. The previous owner had it tuned for 60lb injectors. I will be using 42lb'ers. In between installing the supercharger and getting to the dyno. Should I use the Pro-m. Can I send it to my tuner and have him roughly calibrate it for 42's till I get there. Should I use it at all. Suggestions? I plan on around 10lbs boost. Around 400rwhp. Thanks.
Okay so I'm getting close to putting my Procharger on in a few weeks. Just need to fins someone to weld on my full length subframe connectors on. I am still a little confused about my Mass Air sensor. The Pro-M I have is calibrated for 60lb injectors. I will be using 42 lb injectors. My dyno is 2 hrs away. Should I just use my stock MAS till I get to the dyno? Should I mail it to them and they can calibrate it and send it back? Or will the Pro-m be okay for the drive down. I do have an X-cal 2 so I will be loading a tune just for the ride to the dyno. Also I have an AEM wideband so I can keep an eye on my A/F. I just need to know what to do with the whole mass air sensor deal. Also can anyone recommend the best supplier of the supercharger tune for my x-cal. I bought the x-cal from AM. Thanks.
IM not really sure why you even using that MAF in the first place, but the car wont run with that maf and 42#ers. YOu really should be using a stock maf or the diablo maf-ia is also good, because it extends the range of your stock maf.
The MAF came with deal I made for the Procharger. I just assumed I needed to use it. So I will be okay with the stock MAF? I've heard of the MAFia but I figured why spend any cash when I could use the Pro-M. Your thoughts ?
Unless you're going to bump the boost up pretty good you shouldn't see pegging of your stock maf (you'd really want a built bottom end for that anyway). If you do I'd probably get an SCT2400 MAF or a maf-ia. In any case the proper way to tune AF is by maf transfer function so all the "calibration" is for jack. You could have it re-cal'd for 42's but I wouldn't use a Pro-M myself. The guys I've been learning to tune from seem to hate them... I'll defer to that.
Thanks for all your advise. I'll just stick to the stock MAF for now. I just didnt want to get to the dyno which is 2 hrs away to find out my MAF was pegging and have to settle for less power. Thanks again.
Then sell the Pro-m and buy a diablo Maf-ia and bring it with you. If you need it, then install the mafia; if you dont then you can return it. Thats what i would do to be safe cause it would suck to peg the maf and be stuck.
Bwhipple, I'm rethinking some of this. The ProCharger setup typically uses the MAF in a blow-thru configuration, which will peg a given MAF earlier than when used in draw-thru, so a Lmaf MAY not even be enough. Something else to consider is that most tuners want the IAT after the blower, and post intercooler if so equipped, to monitor and adjust for air charge temp. Your '03 has the IAT built into the MAF, which is good, no adding a sensor or rewiring, but it prevents you from using a Lmaf/'03 Cobra MAF (same thing). I would try a MAFia to get more range out of your stock MAF, and if it won't cut it, get a BA2400 (which also has the temp sensor built in).
forgot about the 03 thing... I wonder if you can install the 03 sensor in the 90mm body... it's just a little bit of hole widening at worst and then a hand curve to the MAF xfer functino. The sensor plugs are the same... just the hole is a different shape and there's a platform that the IAT sets on apart from the main sample tube. I think it would probably work that way... not super easy but not impossible.
