    How are things running now?

    I just installed mine and will calibrate the IAT tonight. Hoping to get some good logs in and setup my tables before winter hits. I will not have a MAF come summer. I will post back on my experiences.

    So i have a few logs. I have adjusted the load values on the secondary map and straightened out the values so lines do not cross. What else can i gain from the logs before trying to run on SD?

    Careful when adjusting it so the lines dont cross, sometimes for what seems no reason at all they will get all tangled up again.. not sure what causes it but it tends to piss me off an from what I can tell is it only does it when you are using the graph. So double check!

    I got rid of the MAF last fall before i put the car away. I had to cut the fuel map values in half (100 down to 50 at idle) to get it to run. Not sure if i missed something or what. I set up the IAT table according to my readings with a cup of water and my Fluke temp probe. I did each point in the table to get as accurate of a table as possible. Is there something i should look at on why it would be this far off? I was logging runs with the MAP and IAT connected for a few weeks before switching and everything was good. I will be doing a few things before i will be starting the car again, I just needed it running to get it on and off the trailer.

    You CANNOT use the same fuel map style for the SD fuel table as you would for a MAF.

    I suggest importing the fuel table from a SD calibration in the startup cal folder.

    A picture explains this quite clearly:


    I almost did the same thing when I installed my MAP sensor

    I have not messed with the software since last fall, while data logging does it log the MAP fuel table value as well? This would help me more accurately set up the initial table. I will update the software this weekend and start poking around to get myself familiar with it again.

    Yes, "Fuel Map Value" is logged on the "Data Screen".

    I knew it logged the "Fuel Map Value" but I was wondering if it did the conversion and also logged the comparable SD Fuel Map Value when running off the MAF. I updated the software and reviewed some logs but it does not log the SD value. I imported the fuel table over from the SD start up TCD. Since this is NA I copied over the load (20-100kpa) and RPM scales, then copied the column at 102 kpa and pasted it at my new end column of 100 kpa. Then I extrapolated the cells in between to get my new table. Once I get the car back together I will tune from there, does anyone see any issues in doing this?

    Thanks as always for your help

    Lol, bro I don't think that's how it works.. wish it was..

    Your going to have to start from scratch on the sd fuel map But the one thats provided with the sd tunes is a good starting point.

    Can anybody share their tcd file for the map sensor setup?

    No, your going to need to start with the one included in the nismotronic start up calibration folder, nismotronic isn't like nistune or calum where tunes can be shared so easily, there's more involved, setups differ..


    Once u get the tune loaded tailor it to your setup, meaning set your wideband up, map, iat, and whatever else.. like injectors and Maf..

    You can always shoot me an email and I can help you get setup with a file that will at least get you in the ballpark!

    I always thought it would be a money maker if someone made a VE tube with the bung and elbow for the iacv at 2.5 and 3" - much like *gasp* overkill engineering motorsports did back in the day for our VE's but with the MAP Bung in it. I'd pay for one, and I know I'm not the only one - sick of looking at my ghetto fab job.

    The map sensor plugs into the manifold..

    The iat does go into the intake pipe tho.. I been learning to weld, maybe I can come up with something

    Iat yes that's what I meant sorry the photo on nismotronic website shows an excellent example, though the bung should be inward facing so it's not so obvious

    hello everyone,

    we are trying to do the conversion from maf to map on sr20ve engine. we strictly follow the wire on the map instruction in the nemu website. then get a vacuum coming from manifold.

    however when trying to use the standard calibration. the map reading on idle is around 700-900 mbar. do i need to adjust the scalar / offset to correctly get the correct reading on the map? i would like to know if what is the normal map reading on idle for gm3bar map.

    Thanks

    700mbar is around 20inHg, which is about right.

    Thanks man for the quick response!

    So basically 600 -700 mbar is fine on idle. I thought that it should be around 90-100ish something similar on the maf load. which is around 10-20 maf load on idle... atleast i have the ballpark.

    So i guess I should start on that setting then i'll try to do some adjustments!.

    will update..
