Anybody out there know what options the n/t enthusiasts have to upgrade our ECU's to match the mods we have? The turbo guys have a few choices to either get some new chips to change the fuel curves and timing curves and all that good stuff. And there is also the stand along computers from AEM and a few other companies to help them out, but is there something for us as well? :confused:

Has anybody gone this route with a n/t to give suggestions on what to do?

Any help at this point in time would be much appreciated! :thumb:

There are EPROM N/T ECUs for 4G63s out there. Just get one and socket it, then you can change parameters and maps too.

Steve

So if I already have an Eprom ECU, how do I go about changing the parameters and maps. Do I have to send it in somewhere, or do I purchase a chip from somewhere and then install it myself?
 
i doubt you already have eprom already, check tho it should have an E in there somehwere......they came in 95's if im not mistaken.
 
2 suggestions

if you want to tune a little just to get a few things straight
greddy e-manage

if you wanna go all out

aem ems

im gonna try ther e-manage at first but have a feelign i will be getting a ems

Note that he has a 1G according to his profile. I've seen several 1G N/T EPROM ECUs but never bothered to write down the year they were from.

You would need to get the ECU socketed and then spend some time getting intimate with the N/T code to figure out what you wanted to change. I'm not aware of anyone making N/T chips due to the small market and sigificant differences between potential customers. The point was for the really high end N/T guys there is the possibility of using the stock ECU as tuning platform.

try the e-manage backed up by a safc. that will tune anything you could possibly want. you can run up to 450cc injectors on a 1g n/t. youll need the resistor pack and all and use the safc to tune that in. if you wanna go rock solid get a data logger and see what your timing and ignition looks like.

see what your afr looks liek and such. if you run all 3 things, the safc,e-manage,and datalogger youll get every peice of info possibly.

or you can go nuts and use the aem ems and you can do anythign
 
Ok guys, appreciate all the help. :thumb: Just to let you guys know that 92-94 n/t DSM's had Eproms in the early months of those vehicles of that year. Mine has a Feb. stamp on it, so I managed to be forturate enough to have one of the few. I just wasn't sure if someone made chips out there for the n/t's or if we had to go the other route as mentioned above. This option may be far off in the future yet, but I was just looking to research my options before I came too close.

I'll see if anybody has a copy of the EB20 version code for the NA.
I suspect that there were AT EPROMS from the same time period but I haven't seen one. I'd like to find out what code base they used and update my list.

Steve

Appreciate all the help Steve! :thumb:
 
every bit of that motor needs to be tuner to perfection to run that kinda power on a n/a motor. every all motor class guy without a turbo isd runnign a stand alone engine management system. you need ot redo the fuel maps, the ignition, everything. the mas has to be tuned and all.


and yes i have seen these all motor class cars and talked to the drivers. every oen of them has there car tuned just as much as turbo car. even the isc and stuff gets tuned in. theres a lot involved in gettin a n/a motor to that power level

Yeah, I am definately looking for more than just increasing the amount of fuel I am getting. I would still need to play with all of the maps in order to change the curves for the ingnition as well. It is better to do it right the first time then trying to play around with a bunch of toys. I will be starting with the basics however, like the pocketlogger, and a S-AFC II, a MSD DIS, and whatever else I need. But this doesn't really help with what the stock ECU wants my car to do compared to what I want it to do. Some things still need to be played with after those add ons. That is where I was looking for the advice on what to do next, after the basics are taken care of.
 
if you go aem ems youll have so much more versitility to the tuning. you can do anything.

if you were to build a n/a race motor that you would need this for it goes way past bolt ons. the main jey to a n/a motor succes is the head setup. you cant really go big as you need port velocity as we do not have a turbo pushin this air in for us. we need to be able to get a lot of suction through the stock ports.

kinda liek if you were to blow through a 6 inch pipe, the do the same thing through 3/4. the 3/4 would have more flow and a higher pressure rating. same thing with the head ports. if you get the head right itll have the stock size intake ports and exhaust ports but have bigger valves and cams in it.

also you can run up to 11:0:1 compression on pump gas, anythign over will require race gas. the stock rods are strong enough for any n/a setup as the 1g 6 bolt had big rods in it which can handle 450hp. everythign after that is bolt on.

the pulleys can be underdrive to give a big gain when the motor is built up, the intake and all. runa mas translator setup and all that good stuff. put on a 2.5 exhaust and youll have a beast of a n/a setup.

i could go on for a logn time with this but if you really want to build a serious n. motor pm me with any questions. im gonna build one this winter.

Most of this work I have already accomplished. I decided to stay at 10:0:1 for the simple reason of adding nitrous at some later date. Otherwise I have the rods, pistons, pulleys, exhaust, and the CAI with MAFT already in. Looks like we think the same way! :thumb:
