I understand ... thanksShort answer here is that you are in a public forum, have invited the public to comment. You can't have someone "removed" from a thread simply because you don't agree with what they are saying. As long as nobody here violates the terms of service, they can say pretty much what they want. You can disagree with them... you can even IGNORE them... but the moderators of this forum are not here to coddle you. If you don't like the way some people are going to answer your question, don't ask everyone to comment by posting on a public forum.
Thank you for your attention... we now return you to the ongoing thread.
I already know this as i already mentioned this several times ... I just don't think they are understanding because they keep hitting me with the same things rather than explaining to me WHY ... I KNOW pressure is different from CFM ... So they keep saying because your new turbo at 14 psi will exceed the ecu's limits and throw it into limp mode, etc, etc ... after i TOLD them that i would be MATCHING cfm from one turbo to the next ... NOT pressure as they keep referring to ...p.s. Volume vs Pressure... not the same thing.
Yes i know this already ... A MAF measures cfm or volume so as it measures more volume, the ecu will account for it... My nissan has a MAF and i went from a smaller turbo to a larger turbo without a tune because the MAF accounted for the extra CFM at less pressure ..If you had a MAF sensor instead of a MAP sensor, you might be able to get away with a larger turbo without a tune... but you don't, so you can't.
This car does NOT have a MAF... it has a MAP sensor which only reads vacuum and pressure ... So it does NOT know how much CFM or Volume its getting ... Only what the pressure is ... SO with that said the only thing that can be done is to match the CFM flow rates from the smaller to the larger turbo.. Make sure the new turbo does not get too high in pressure to where it out flows the stock turbo's cfm rating to keep the a/f ratios the same ... So if the stock turbo flows 1000 cfm at 17 psi, you make sure the new turbo flows NO MORE than 1000 cfm which would be around ~8 psi or whatever psi that comes to ...
Am i in the ball park here or an i still wrong..??
