N-60 mafs and 370cc = no tuning????

[Zippy69]

I have searched and searched this site and others. But I can't find a definitive answer. I have read it here and on other sites that you can run an n-60 maf s with 370cc injectors and you won't have to do any tuning because they sort of cancel each other out. I don't know so that is why I'm asking.I need to know if anyone is actually running this set up or if they haveFIRST HAND knowledge of it.If it is possible, then what are its limitations? Boost level, output etc.I have built several set ups using an FMU and have had better results than any set up that used a tuned ecu or a safc. Much less problematic.I love the ease of an FMU set up but would like to make more power.Thanks.

You would still need a SAFC to set the maf correctly, and then you wouldn't have to tune fuel, but you'd still need to tune timing. I thought about this, but if you're gonna get a safc and all that, might as well get a N62... just my opinion

The only way is to simply try it out. Since the N60 and 370's are a good combo regardless it won't hurt to try it. I don't think it will work though, I doubt the stock ecu will be able to read the different MAF voltages correctly.

IMO if it doesn't work, lose the AFC idea and get an EMance Rom tune. $150 for the win.

The car will run fine, I did it for a few weeks recently, but you definitely need an SAFC to tune it correctly. Mine probably ran at 9:1-10:1 AFR's or so. what's this emance rom tune you speak of?

hell i ran an N60 MAF on my stock ecu and stock engine for a few months, because i screwed up my stock MAF. it works great just for a replacement MAF.

GTFO??? How has this not been spread around? Or am I seriously that far removed

Thanks guys. I appreciate the info. I heard that you didn't need to run a safc though, that the mafs and injectors worked at the same percentage, making it so the ecu didn't have a problem.The whole reason for this is to keep cost down while still having a fun car for a beginer. I've done several FMU set ups and they have been great. but if you wanted to run a larger turbo, then the n-60/370cc combo would be awesome and readily available.Hopefully more will post with something definite. Oh and Emance tunes and sockets ecu's

probably because it's still not recommended. Like I said, I was easily dipping into 9:1 AFR's, and car was pretty much running like a turd, but it still ran reliably. I mainly just did it because I wanted to see if it worked. I don't know how it works, but it does..

And honestly I've only read of 2 other people trying this setup without using any tuning at all. They were both from KA-T.org..One of them ran this setup for at least a few months.

Well, you actually proved that it doesn't work. Not that your car didn't start and drive...

Anything in richer then 11:1 is very bad on the motor as a whole. Fuel enters the oil, leans it out and that can effect everything from the oils ability to lubricate the motor down to the oil being able to pull absorb some of the latent heat involved. Not to mention you get extreme carbon buildup.

You can also wash the oil off of the cylinder walls and score/scratch them bad enough to cause a serious compression leak.

SO for anyone else reading this...

IT DOES NOT WORK

There are FAR better options to use.

I can confirm this, because I did the same thing (on an S13 ECU). I didn't have a way to monitor my AFR, but the car ran perfectly fine like that. Drove like a stock vehicle.

[WDRacing]

The main problem here is that a car will run and idle great at 10:1 AFR...so just because it starts and runs does not mean it is working like it should be.

I'm currently running my car this way n60 maf and 370's. I had an safc, but it got stolen about 2 months ago.

Anyway, the car does idle rich. But I also have an adjustable fpr, so I turn down the fuel pressure until it idles nicely and has good response(usually between 35-40 base pressure). I've had 2 drift events since then, so I turn up the fuel pressure to around 50psi so I dont run lean in boost.

I wouldn't recommend this setup though for the simple reason that you don't want to cheap out on setups. I also don't recommend safc. A proper, cheap setup would be a calum ecu.

Not only is this a bad idea, it could lead to serious motor problems.

This is a bad idea and does not work...period. Don't do it...
