4Y EFI Conversion - Chapter 2

[BenHur]

Eric

Whenever you use the Dicktator software the 1st time it asks you to calibrate. But yeah I have seen that certain USB connectors does seem to corrupt the data on the ECU I guess it does not download properly or something. But normally you would be able to spot issues like Louis did when the programming on the timing and fuelling is all the sudden way out. I guess certain USB to serial adapters just is full of nonsense. Mine does not affect the Dicktator programming but it seems to go into sleep mode very often if my laptop runs on Batteries, but there is nothing in the Laptop's Power management setup that can be set to disable it from going to sleep.

I guess that was also the same thing which made Louis ECU appear to be loosing its memory. He also has a funny USB to Serial adapter.

Glad to hear your flat spot is gone.

Bennie, the difference is incredible. What irritated me no end was the fact that Bulldog would keep stalling on idle with the a/c running, and this is why I looked at it with the Dell. I had already copied the mapping software into the Dell so I started BD and let the car idle while adjusting the revs, after first having calibrated the PC with the Dicktator. On an impulse I decided to just dump the (original) software into the ECU and took BD for a test drive. The results were immediately obvious!

I can only think the Acer had never been calibrated before or the RS232 converter played around, but the difference in available torque is simply incredible. I had been planning to contact you to ask Schalk when I could bring BD up for a new Dyna, but that is no longer necessary. Acceleration throughout when accelerating is now far more linear with no hint of any flat spots or sudden power surges as I was getting and BD now maintains speed on the open road better than before the remap.

Oh, and the idling is now also perfect :)

Hello everyone. I have been following this thread quite in depth as I would like to convert my 2.2 4Y to EFI. I may have it slightly easier in sourcing parts as i have a complete Jap import 3Y-E (2.0 EFI) engine.

For now though may i just ask, has anyone needed to change the alternators for a higher amp unit. From what i have seen, all the carb Y engines run a 40amp and the EFI (3YE and 4YE) run a 60amp unit.

Is the extra power to help run the injectors, ecu etc or more to do with the higher spec of the vehicles. ie, having full electric windows + mirrors, air-con etc

ta,

matt

Hi Matt,

Welcome to the Forum!!! I hope you enjoy your stay here!!
To answer your question, it is advisable to change the alternator on the 4Y if it has a small capacity output. I had to change my 4Y alternator because I could not get it to charge anything above 12.9 V.

I opted to fit a VW 90 Amp alternator with a special 8mm wire running from the Alternator to the battery. Now I have a alternator that charges at 13.8 - 14.2 V.

The reason why the 3YE had bigger capacity is to carry all the extra's and the Injectors ect.

[Mr_B]

When I did my conversion and installed a decent Bosch HP fuel pump(replacing the dead cheapie pump)... the fuse for the pump and injectors blew once or twice, it was a small fuse, about 10/15amp... i replaced the blown fuse with a 25amp... no more blowing... this indicates that the current draw of the Bosch pump is higher than the cheapie pumps... so having a decent amp alt(90/120) can't hurt... especially if you plan on adding other current happy items, like spot lights, a winch... etc...

I see, thanks for the info. I did wonder if it was something like that

My next question is perhaps a little more involved.
Since i have the full 3Y efi engine, loom and ecu. I was hoping to transplant the efi onto the 4Y. (The 3Y has a bad crankshaft) Mechanically, as far as i'm aware almost everything is a straight swap to the 4Y. My real question is, would the 3Y 2.0 ecu adjust itself to correctly manage the 4Y 2.2.
I understand the best way to do this would be to use a new engine management and get it all dyno tested but thats way out of my budget. I have also looked at the proper 4YE ecu's but these are expensive and it looks like the wiring loom and a few other parts are different

essentially, i am after a good fuel economy and plenty of power when i need it (which wont be often)

cheers
matt

[Mr_B]

If u after plenty of power a 4Y simply won't do... then you should look at a engine swap... 7mge??

I'm sure the 3Y ecu will work fine... as long as all the sensors are fully functional... but you won't be able to tune/tweak it for your needs as all the setting are preset and fixed(non-programmeable)... so a aftermarket ECU may well be a good option... remember the humble 4Y is a pretty simple engine, so a basic decent ecu is good enough... you won't need some mega sophicated, expensive unit... the ecu we used is design and manufactured in SA, Dicktator... and exported to Germany as well... so it can't be too bad... and at R2100 (about 200 pounds) it's inexpensive!

mr b

[matt_uk]

yes i'll give it all a good check over before bolting it on. from what i've read off here the 4Y with efi should be enough for my power needs. i've seen a few 7mge conversions which look great but i'll pass on the work involved for now.
most folks choose a rover V8 or ford V6 in the uk. but to much power kills gearboxes.

a Dicktator for around R2100 (£200) doesnt sound to bad. i was told around double that plus setup and dyno testing

Hi FD

Could you please advise on the following for me.

1. What CC (flow rate are the injectors)
2. What size is the throttle body that you use.

I have the EMU now and get 4 220cc injectors and possibly a 40mm throttle body. I just need to know how far off/close I am.

Looking at making my own manifold up(still in 2 minds)

Your help will be much appreciated.

Thanks, Zane

[Toybox]

Zane,

I do love to tinker, but why make up something that you can get so easily?

[Family_Dog]

Zane, I have no idea. The injectors etc all came off an imported 3Y Jap motor, and are a direct bolt-on fit to the 4Y. But as Jonathan says, it is far cheaper to purchase the whole assembly second hand from an engine importer, new parts would be very expensive.

FD

cheers for the response, it's mainly just a matter of trying to make a system for less.

Don't get me wrong, if I had the money available, I'd most defi buy the system complete and not battle.

Cheers

Zane

[Toybox]

Then keep looking matey. The last time I called around (admittedly it was a year ago) I could get the manifolds complete for about R500

[blouaap]

Hi all,
Happy New year to you all. I fitted my dictator and efi system and, it will not start. I've got fuel and spark but no joy.
while I was fiddling with the dizzy I managed to break off one of the chopper blades and can not repair it.
Can someone please advise me of what replacement I can get and where, also I don't know if the angle in the dizzy was right , still can't get the idea of how to set it up through my head. Will recheck my wiring untill I can sort out the hall sensor and chopper.

[The Legend]

Replace your dizzie with a electronic one.

[Ou Legend]

Morning I have 2 Efi dizzys built by Louis up for sale,I got Spitronics now and use cranc sensor with coilpack,inboks me.

Hi manne het onlang vir my n 2.2 hulix gkoop. Hy ht n 32/36 weber carb op , wil hom feul injection mak. Weet ni wst het ek alles nodig n weet ook ni waar om vir parte te begin soek ni. Het ook maar n limit van fondse as julle my sal help sal ek dt waardeur danki

[Family_Dog]

Nico, kontak vir Louis by 4x4 Megaworld, Menlyn. Hy sal vir jou advies kan gee, of dalk die hele job vir jou doen.

[Asjas]

Yes guys I also done the 4y to efi conversion on my Suzuki sj410, anyway I did it in 3 days and gave it a rough tune. I opted to use a gold dizzys internals in the stock dissy and seems to work fine.
Anyway I tuned it but she runs a bit rich. Would it be possible for someone to send me one of their maps so I can get the fuelling and timing right.
I'm also available if anyone needs info on the efi system. Sorry for hijacking this forum.
Thank
ASJAS.

[LouisZ]

If you don't move the rotor phasing on manualy or in in the Ecu on by 40 degrees you wont get the performance of it.

[Asjas]

I know dicktator and use it both in my 500hp turbo mazda and in the sj.. Only problem earest dyno sits 130km away...
So i basicly just need a map to sort out feuling on it.

[Scott]

I have 4Y efi manifold/ 2x Mr Turbo units/4 x injectors open to offers

[Mr_B]

Not sure if this will help, but here is Bolt's original dyno'd map:

http://ftgsys.co.za/map/4Yi-Dyno-Orginal.zip" onclick="window.open(this.href);return false;

Please download it if you want it, as I can't leave it online long.

[Asjas]

shot thank you very much. did he also use dicktator

[Mr_B]

Yes, it's a Dicktator dyno tune map, note that it was at sea level, not sure if you will need to tweak for altitude.

[Asjas]

That should not be nesasary as im at altitude. so air presure wil be lower. actully nice if it works then i can go down to the coast without to much warrys

Hi
Sorry to fall in at the time but I have a 1997 2.4 and will like to consider my options.
What is the cost regarding the EFI conversion and what other small (cheap) upgrades can I do for better fuel consumption and a bit more power?

[LouisZ]

On the 2.4 one need to source the intake manifold from the Usa. Only place you get them from. Make sure you get it complete. Ie the top and lower manifolds, 4 injectors, fuel rail and fuel regulator and the throttle body. It goe for average $150 and the rest for freight import will be another estimated $200.

The rest is easy, ecu and pump and odds and ends will be R6000.

[Jeand4dSteenkamp]

Thanks LouisZ
I have branches on my bakkie, will this have to be replaced or should it be fine?
Do you know of anybody in KZN that can do this conversion?

[LouisZ]

On the 2.4 branches wont matter, do not have to be changed. Its a cross flow engine, it means the outlet sits on the left and the intake on the right.

[Stef]

Jean, it is super easy to DIY..I'd say one could do it in 2 days if you have everything sourced & ready to go.
I took about 2 weeks due to the HP pump & plumbing as well as a few odds & ends I had to source and manufacture...but all the hours of actual labour added up to 2-3 days.

[Jeand4dSteenkamp]

Hi Stef
Dankie baie en dit lyk goed maar ek sal nie so iets kan regkry nie.
Glo my ek wens ek kon.

My bakkie het n nuwe carb op so ek is happy met hom vir nou, het maar net gedink dit sal n maklike ding wees(maklik vir julle).

Dis nie so erg nie, as jy kan "spanner swaai" is jy 80% daar

[Ogre]

I also need the EFi conversion done to my Hilux, who does this type of work here in the Joburg please?
