What I'm really worried about is it seams that my Ecu is too slow compared to all the new stuff i've upgraded.. Not having the possibility to run lots of boost, even lowering boost its still to quick for the Ecu. I was thinking about getting another external boost controller, but also thinking about buying a different standalone Ecu with VE tuning.
My goal is hp but really love seeing the turbo in full boost 1. What would you do? Or would you change the Ecu? I'm sorry I didn't explain myself very well.. What is slow is the ecu to pc communication.. My AFR is on point! Its a AEM uego. The readings are good and quick as other compared on the car. A brand new uego and a brand new Innovative.. The pomblem I have is that while i make a test run and log it, the communication between ecu and pc seem's to be to slow.
I seem to be missing many spots on the graph.. It's no doubt that communications between ECU's and computers now are a lot quicker than when the PFC was designed back in the 90's. Are you datalogging onto an Excel file or just using the ghost to see which cells the ECU is hitting? I don't usually have any issues with coms, are you sure your laptop is running clean? I always shut down everything non-essential when mapping to map sure nothing is using the computers RAM and slowing things down.
I bout a laptop just for tuning.. Also tried another laptop and guess what.. I tend not to use the Excel file for recording the dataloging as it does as you describe and miss boxes, the usual reason for this is because you've passed through the cells quickly, try using a higher gear to slow down the rate of acceleration, just keep an eye on your road speeds.
My new mechanic isn't really convinced of the pfc and he keeps telling me i need to change it with a Efi euro 2, which he doesn't even sell or install, and he hates that z32 maf.. The Z32's serve a purpose, I've started using Z33's as they are a quarter of the price of a good Z The only trouble is getting a hold of the plugs for them.
I bout a brand new z32 maf. I didn't know you could hook up the z33 maf to the pfc.. I've heard people using the GTR maf cause of the low price new! I'll need to look this up, its interesting.. All of my d-jetro manuals are in Japanese, if you have any specific questions regarding tuning then ask them in the forum, someone will be able to help you.
Sorry bout not writing anything at all lately, but i was very busy. I also was able to sell my Apexi Power FC. I have decided to change ecu and get some professional help. Not only the person will be letting me assist in all the tuning process, at least I can do a hands on and compare the fantastic HP lessons! Don't have an account? Register here.

Apexi Power FC… Is it still good for the job or is it best to upgrade? The maf that needforZ is talking about is the 90's maf. I've never actually tried fitting one but I have seen them up close, and to me it looks exactly the same as the one that is used on the z The z32 maf can be used, has the same rubber boot size but needs a flange one the one side.
Plus you will need to re-tune the ecu to read that maf properly. In which case you had better get your hands on a ecu that is retune friendly. I was wrong. My previous post has been edited to reflect this. Sorry about that. I have seen several maxima's with z31 style mafs, that's why I posted.
Thanks for the good info. No problem Bernard. I did not mean to sound harsh or come off sounding like some kind of an MAF expert. With all the misinformation on other forums, I take pride in making sure that the information on HybridZ is as accurate as possible. You can use NA ecu's. I am running a 88NA reman ecu on my car with no problems. As long as the chip inside is square it will work. BTW some 88maxima's work as well.
ONLY if it is a tuneable ecu. Not good for a turbo, you want something that will retard the timing as you hit boost otherwise you might grenade your engine. If the ecu is tunable, you can always make a new advance curve.
A ecu that is tuneable should have a 28 pin eprom chip on the mainboard. All you have to do is pop the cover off with a 4 phillips screws and have a look. Or you could always get the number part number off of the ecu to find out the year and application.

Is there a support site somewhere? Bernardd 4 Posted October 11, GrayZee 2 Posted October 11, Posted October 12, GrayZee 2 Posted October 12, I can get a flange adapter so it will have both ends to fit the pipes.
