Engine choice

Proudly South African (as long as you can afford the petrol 😁 )

RBSX has got me to condsider a 1JZ motor over a SR. Thought behind it was a bigger engine with less stress. Would cost less than beefing up an SR motor to. Damn, :200sx_confused1:

Good for you Veecee.

There are allot of “IF’s” in that statement but you can use what ever management system you want it’s your car and I not stopping in fact I don’t really care. Good luck with wiring the thing in and tuning I have read through the Gotech Pro and it offer around the same features as the stock ECU, But on the other hand I wont be able to use a Map sensor LOL but I will have a selection of great tuned “.Bins” from a number of big tuning houses like Mines, Norries and so on and I can get the Knock Map to save my ass should I have a bad tank a fuel.

I have all the nice Cold start stuff, I have deceleration charts to save fuel , I can change Dwell time on my coils should I swap to GM units so fell free it seems to be the only down side is the MAP sensor and I have given a solution , I will just plug my wideband in do a full “datalog” to fine tune any drops in the AFR

oh, ok then.

You know what, I am just going to back down on this and leave the forum with this go check out the Nistune website download the software and work on it then get you hands on the Gotech Software

Now look at your needs where and for what will the car be used for and make a decision if keeping the stock Nissan ECU, mind you probably with a Bigger AFM and injectors but with all the nice drivability and the easy tuning with good fuel economy or if installing an aftermarket system if its an all out race car that needs launch control, Shift lights and so on also remember there are other cost not based on the ECU its self like trigger wheels, Coils and so on that might need to be changed, Wiring, tuning if not done by yourself and the constant need to change the MAP should you make any mods that effect VE because of the Map sensor.

If you don’t have the stock system then it will be more expensive going this road ,if you do then in my eyes it’s a way better option then anything for the price range but have a look at the EVO and STI forums and sites most track day monster are using the stock systems because the R&D does not and can not compare to what most manufactures put into there systems it’s the best overall package

I agree with the fact that It is nice to have all the stock ECU functions and all, but its not always possible to keep the stock ECU ie: changing the ENGINE would require different management and if I am not mistaken this thread was started with different engines in mind. 😮

True that Ero_sennin my Mistake. But most comment made where not about that fact but was focused on functions of each tuning system

Yea, i do sometimes wish I had the stock functionality of old ECU for certain little things, but hey the after market was necessary and has some bonuses.

this has turned out to be quite an entertaining thread.. 😂

i have to agree

Glad I could help... I think 😂

PFB makes some good points.

My feelings?
XMS, nice system, when it works...
Dick and go, they both are nice for race, just not enough resolution for street.

Problem with the dick and go is that they just dont have enough programable load & RPM points to really take advantage of mapping in a turbo motor especialy when it runs higher boost levels.

For a NA car they work mint, for a very low boost motor (.6 bar) they also still work semi ok, but as soon as you running decent boost like 1.5 bar it means that you can only map in 20% stages so like 1 in vacuum 1 @ 0 and and 3 in boost? i dont know about anyone else but the thought of programming at 1bar and then only again at 1.5bar is just stupid,

Think thats 25 programable points,,, near all decent managment systems use a 20X20 map = 400 points.

The key to making good reliable, usable and stable power along with fuel consumption when your not on the loud pedal is the ability to map it at all the desired points, good example is Myprodol's car, 11km/L at 130/140 and ran an 12.2 on break in boost... should get even lighter on fuel as everything finnishes seating.

Now, the next fun thing is finding a tuner that will actualy know to map it, let alone how to make it run perfectly at every point, bet you with the fuel prices these days though its worth spending the money doing it right the first time, probably save R150-R200 fuel per tank with a properly mapped ECU with a decent resolution.

For a race car when your turned off or all out the basic systems work well, for street, i would want as many load points as possible.

I fully agree with you RAW. Problem is there are not many people in this country that can tune a decent system (or any system) for that matter. I know some guys in DBN that dont even tune all the sites on the tator let alone a 20x20 grid.

HAHA!! 😂 😂 😂 😂 😂 😂 😂 😂 😮 😮 😂 😂 😂 😂 😂 😂

jup RAW and Gary are right, I need to get my XMS tuned properly cause it really runs good for those lets show the GTI what a fast car is runs, but when driving very carefully under 2000rpm fuel consumption just sucks balls

I just wish I knew wtf all the stuff meant on the mapping software, altho I know how to change the PRIME haha, I would tweak the maps, but seeing as that I don't know what does what and how ratio's must be i'm sitting with a map I suspect is way to rich.

Dammit. Ok thats the end of my rant

who calibrated that XMS of yours??? 😮 😮 😮

its more like

so...

on my gotech software there are 32 programmable load sites for every 500 rpm.

so some basic math:

7500rpm/500rpm = 15.

32 load sites and 15 RPM groups.

so 15x32 = 480 load sites.

is that NOT enough???

or am i being stoopid too???
