I have done it with zero issues. I highly recommend it over the stock 20ve ECU. Rev cut is around 7800 I believe. Injectors, and MAF are indeed the same.

That's interesting, cause there is a girl over here in NZ that has tried the 16ve ecu in a 20ve and it ran REALLY lean.
16ve ecu runs different ignition advance and the fuel maps are different compared to a 20ve ecu.
16ve rev limit is 8200, compared to the low 7200 of the 20ve ecu.
I've also hear of someone else who ran the 16ve ecu on a virtually stock 20ve and had a few issues with big flat spots in rev range....but as mentioned about, others have no issues....could be the different fuel?
The mafs are not always the same. The 16VE and 20VE roms I've got have different VQ maps. Compare for yourself.

Calum, I have checked both my MAF, and a MAF from a sr16ve front clip where I got the ECU from and the part number was the same. What adr file are you using to compare the two? I know the one from the ztechz forum that you put together had some inaccuracies.
emm
the issue is some people using on 20VE retaining stock 20VE cam
my case is i use 16VE cam .
Im the guy that uses a VZR ecu on 20VE motor. Use to have the problem that the motor ran very lean but have learned in the meantime that we were running the old DE Maf. Since changed to a VE maf and boy,what a difference. I now have bought another VZR ecu for anyone who wants to upgrade

If its the same address file for both roms it would be pulling the vq from the same address in the rom, vq map values are off but iirc not by much, and since its pulling from the same place it cant be that one map is shifted. Then again there are other nissan roms with 2 vq maps. Who knows what nissan is doing.

So your now using the sr16ve ecu and maf and not having any issues? have you redyno'd the car since? as I seem to remember you where down on power by a fair amount....?
have you compared the sr20ve ecu to the sr16ve ecu now your running the correct maf?

That one. The VQ table is correct. We need to figure out what exact engine those ecus go with, I think there are more variations of the VE floating around than people think.
You also had bought that computer from South Africa to try?...that was a big failure then?
The problem with the piggyback was that we couldnt get the trigger pattern. That company are now building a piggyback for Nissan specific. They have learned from their USA agents that there are a huge demand for something like that. The piggyback they sold me are used with huge succsess but mostly by Volkswagen users and that uses a different trigger pattern that we are using on the Nissans.
