Do i need a bigger Maf?

[Got2BeBoosted]

So what is the difference i getting one of these cables on this site instead of just getting one off if Nistune when i order all the stuff i need?

Same Consult cable. Just buy it together with Nistune tuning software (individual license) + Nistune instead of separate.

thanks for the info bro! big help.

If you plan on buying nistune for diagnosis only and no tuning, then just get consult plug and run/buy Scantech/ecutalk software which is cheap and works for Nissans with the Consult port.
But if u plan on tuning then Nistune is a very cheap option. It just seems there is a lack of tuners using Nistune in Canada or at least southern Ontario.

Nistune is better, as can download tune and see what maps, tables ECU is looking at in realtime. Can't do that with Scantech, etc that I know of. If Scantech, etc does do it, you wouldn't see all of the maps, tables, etc.

Anyone that can tune PowerFC can tune Nistune. PowerFC was based off stock ECU and are very similar with features, except stock ECU has knock maps that you have to disable when tuning ECU.

Nistune is defintely better. Not even a fair comparison.
I was just tryin to save him some money if he was buying Nistune for diagnosis of problems only.

I too run Nistune. But havent done anything productive with it yet.

[Got2BeBoosted]

well I'm defiantly looking into getting Nistune because i need to tune my car and change the timing maps, fuel and upgrade to z32 maf! and its not as expensive and seems to be the better product in my opinion all the people around my town seem to be running Haltech or Apexi power FC and i don't want to spend that kind of money for a Haltech and have no base maps to start out with and power FC is impossible to find for the RB20Det.

That's the good part, it uses the same maps, tables, etc and only needs to be adjusted to suit upgraded MAF, mods. Cheaper to tune. Also with some aftermarket ECU's you need to setup the settings for sensors. With factory ECU you don't.

Stock RB20DET ECU can handle more than the RB20DET engine can produce on pump gas. For most applications it works.

Exactly all the reasons why i am gonna run it in my car soon it will be so easy to tune compared to everything else.

[Skym]

RB20DET can produce around 500whp with stock pistons, conrods, cams (with adjustable camgears), cheap Ebay parts, etc -

Also is running on E85 (Ethonal).

RB20DET should be able to handle 600hp with stock cast pistons, etc. A set of cams probably would have helped that RB20DET reach 600hp at engine.

It's on the Nistune website under result's (photo of engine) -

Here's what it sounds like -

By the time you buy a larger maff, Nistune , boost controller etc and have it tuned you are so close to owning a true standalone. Nistune takes way longer to tune than a standalone so the money you save on hardware you spend in tuning. The result is not even close to using a standalone as well you invest thousands on thousands in your engine and then use the cheapest tuning solution around based on 1986 technology(which is when your ecu was engineered) it just doesn't make sense to me. My 2 cents

[Skym]

I wouldn't say longer, as only have 16 rpm x 16 load maps and Nistune has solved some problems tuning programs for stock ECU have. Seen a tuned stock ECU idle as smooth as a MAP based ECU. But when you add very aggressive cams (around 290-300 duration), stock ECU has nothing on Vi-PEC or Link ECU with idle stability.

MAP ECU has it's advantages due to no reversion problems with turbo's, no restriction in front of turbo due to gauze screens on MAF, can run atmosphereically BOV's due to MAP sensor measuring air at intake plenum, not before turbo with MAF, can run a bigger intake pipe infront of bigger turbo, etc. Also have 21x20 maps, so more rpm rows above 6400rpm where it would run off the maps on stock ECU (need to add enough fuel, ignition timing, so it can rev above the end of maps to redline or rescale the maps) and can have rpm adjustment rows closer together. Vi-PEC, Link ECU are probably the best bang for buck aftermarket ECU's to solve those problems and more.

[LIGHTSPD]

Just for the record Link and ViPEC are not the same ECU no matter what a link dealer ever tells you. The VE calculationis are completely different. The ViPEC is running a new 4 bar map sensor. All boost control logic is completely different in the ViPEC as well as the auto tuning. There is some sharred board as well as software interface development but that is as far as it goes. The Calculatioin of VE within the ViPEC was developed by the ViPEC dealers. As well as the ability to run high or low impedance inj. The knock control in the ViPec is also completely different.

[Skym]

I see. Oh, ok. Thank you for sharing those differences.

[beacher1B0]

Cam, Just for kicks. What would it cost to get Vipec or Link into a r32 Gtst?
And does either have Nissan Consult Diagnostic functions?
