Nistune Forums

I have plenty but i have to dig up all the dyno graphs. S14 SR20det 323rwkw Arias Pistons Scat Rods Metal Head Gasket Tomei Springs Solid Pivots Rocker-Arm Stoppers HKS Cams 272in 264ex Trust TD06 700cc injectors Z32 MAF blow through Nistune S14 board tuned by The SpeedLab This was tuned a year ago....

Look for a wgnc34 stagea loom. They seem to be easier to come across for some reason.

Maybe, but Matt is talking about Australian market N14 which all had sr20de.

It looks like Calum has confirmed that the B13 does have more than one variation of VQ table, depending on model year. However they do all use the same maf sensor part number.

I don't know about the map trace but lets just focus on one thing at a time. Looks like B13 use more than one type of maf. For example 64Y00 and 64Y01 have different VQ tables. This doesn't change the fact that one variation of B13 maf shares the same voltage curve as the s14 maf. Two things need to...

Because some MAF sensors share the same voltage curve.

Nistune looks at the voltage translation table to determine which MAF is being used. When there are 2 or more MAF sensors with the same voltage curve, nistune has no way of telling the difference.

Make sure the base timing is set correctly Ignore the last column in the standard rb25det timing map. It is there for safety only and under normal conditions the engine should not enter that part of the map. So taking that into consideration you can see the real timing that the standard rb25det has ...

Should be 1x32 table.
RPM lookup 1 = 25rpm. So.....

0rpm, 200rpm, 400, 600, 800,... ..., 5800rpm, 6000, 6200.

They are the old variable inlet manifold tables left over from the original ROM Editor address file for the jdm ca18det. They have always been there but nistune previously did not display them It is incorrectly represented as it is actually a single 1x32 table not two seperate 1x16 tables. I'm sure ...

Chances of a 20 yr old injector flowing to exact spec is slim indeed.

There are also a lot of variables besides the injector size that will have an effect on flow rates.

All nistune calculations should be taken as an approximate starting point only.

Speed limit value must be a multiple of 2.

So 4 or 6 is acceptable but not 5.

LHS = Left Hand Side
RHS = Right hand Side

For engines that use dual o2 sensors and/or dual mafs.

On a s13 sr20det today i experienced an error with the injector sizing function. Starting with a standard blacktop map i changed to Z32 maf which worked fine. I then went to change the injector size from stock to 550cc. After entering the new injector size as 550 i applied the change and nistune the...

Only problem being injector latency isn't directly related to flow rate. Simply looking at the factory nissan latency values for different sized injectors confirms this. Then consider aftermarket injectors which have different pintel designs etc. For that matter even the k-value calculations are onl...

Cool, i'll be using 9099 all week, let you know how it goes.

You sure must love all the little differences between the various ecu models. More subroutines for you to code.
