Anyone tried to tune their na-t with the MAP Ecu? Other question. Are the fuel maps that are downloadble on the website able to be work? Or will i have to dyno tune the na-t from scratch(still not quite sure how it works)? If you have dyno tuned it yourself, please post your specs on the car? Is it easy for an amateur to learn/install? This thread is dedicated to the MAP ecu, if you have feedback on your safc/vpc, aem, etc...then by all means just start another thread. IF this thread ends up dying, then it will speak for itself and show that the MAP Ecu isn't too user friendly and that better options are avaliable :sadwavey:

those downloadable maps are just base maps to get you to the dyno. don't boost until you get to the dyno! i know your going to totally ignore that because i did. i had to test it out you know.........but i'm soo lucky i didn't hurt anything because i overboost a couple times :(
i pretty much tuned myself, along w/ the tuner. he's never seen the map ecu before so i made sure i sorta knew what i was doing before i went to the dyno. READ THE INSTRUCTIONS before you waste time and money at the dyno
oh yeah, in my opinion, it is easier to tune in table mode. that 3D graph thing is too hard to read

What year is your car, are you obd1 or obd2? I have yet to read anything good with peeps that are using the map-ecu on obd1 cars. In any case, I would strongly recommend it having it dyno tuned professionally. The maps that are downloadable are just to get you started. You will have to fine tune from that point as all cars will react differently.

A local supra owner/friend of mine had tried using the MAP ECU with his 1995 (OBD1) na-t, and just couldn't figure it out. I know he tried for weeks to get it up and running, but just decided to give up on it..

not extremely hard to do just read up on it. alot of guys run map ecu's and love it. great for the money imo. but ems is always king

i have the map ecu. If you are OBD1 on stock injectors use the vkf.tbl map and change it to 6 cylinders and your car should start and run qoute well. Throw a wideband on there and do some tuning with light load, med load, wot, and cruising as well as deceleration or your car will pop and snarl and blow flames like mine did from the house to the dyno.

how much easier is it to tune a obd2 over a obd1?
and how had is it to change from obd1 to obd2?

2jz-ge obd II cars are easier to tune with map-ecu since you have so much more tuning resolution. For example, in a fuel map cell on my 2jz-ge obd I (karmen vortex), I have a choice between a value of 16-18 to tune my start up idle correctly :rant2: . This results in it achieving a "coarse" tune for that region in the fuel map. On an obd II 2jz-ge car (hotwire), you could choose a value of like 100-200, etc. The hotwire cars have a higher resolution of tuning within the fuel cells, thus enabling you to achieve a more efficient and precise tune with the map-ecu :eek3: .

oh ok, and what is this v8-maf thing about, i know nothing about this

oh ok, and what is this v8-maf thing about, i know nothing about this The stock MAF (mass air flow sensor) is designed to control the stock 2jz-ge 330cc injectors. If you use the 1uz-fe (v8 lexus engine) MAF, it will control 440cc injectors. So, this way you can use larger injectors and still run your stock OEM ecu with a cheap piggy-back fuel controller of some kind (safc, etc). When you use a map-ecu piggy back (thereby eliminating the MAF and converting the car to Speed Density mode, ala "MAP"), it allows you to vent the blow off valve to atmosphere since the car is running based off of rpm points instead of an air flow signal.... :gay:

oh ok, cool, i understand now. I am very interested in the greddy e-manage ultamite for my car. And i am going to be upgrading the fuel system as well so what else will i need to replace?

I don't know of one single person running the greddy emanage ultimate without any problems on a na-t 2jz-ge based car. just something to think about..

I've been running obd1 and its a pain in the ass. My suggestion would be get anything else, unless you like tuning daily :jerkit:
