injection Its alive!!!!!!
injection Its alive!!!!!!
All this talk of carbys has drove me mad. I tried the swift carby (cost me 65$) didn't go any better, lost a bit down low if any thing. So I ve been back to the wreckers this arfternoon and I found a new idea. Mazda 121 db series single point injection. It looks like it will come close to fitting up so the adaptor plate shouldn't be too hard. Il keep yous all up to date.

What sensors does it have?
I am guessing just a o2 sensor for the exhaust?
A mate did the cordia one onto a 12r toyo motor with a custom adapter plate and the sensor into the extractors... only other sensors were the air flow meter, i think.
cheers

I don't think it will really increase the hp (121 have similar rating to a zook) What it will do is prfovide an easier platform for mods (and the dire need to take on steeper angles )
What ECu you using? if it's the 121 i'm positive the fuel maps would be right out of whack, but if it runs then you could start plaing with interceptors :\
And tell us what exactly did you get and how much you pay

A early 90s 121 modle db106 I think. I payed 120 for the lot including the fuel pump.(intake manafold, throddle body, entire loom, fuse boxes, relays, fuel pump ect) What do you mean the fuel map will be out of whack?? Il be using all 121 wiring and computer the only bit that will be suzy really is the block( i don't understand wiring)
Its a wheelbase thing
I think santos may be referring to the torque and power curves of the suzuki engine vs mazda. Zook motors are more for toqure than the maz,
Is there any other tbi 1.6 motors? Just thinking as it may handle better for zooks like mine running a cam/extractors and exhaust.
cheers

Not just that.. valve timing, revs and gearing.
Don't get me wrong i would really wanna know how this goes cause i still have my heart set on a second Zook and having a cheap EFI is what we all been sitting around and moaning about. Once you get it running we can talk about a megasquirt or even the possibility of a custom burn chip that plugs into 121 Ecu (that would be cool)
But $120 for the Complete set up aint bad IMHO.

If one was "thinking" about a Megasquirt one would not bother starting out with anything else IMO. It would be a waste of time, money & effort setting up a vehicle with EFI from a different vehicle and then going to a Megasquirt. Either do it as Rhett is doing, or go with Megasquirt from the start.

i'd have to disagree, you have to build the megasquirt so at lest having the engine running on an OEM ecu you know it's running
and at $120 for the setup it's hardly a waste of money compared to spending an additional US$130-ish for the kit then you need everything bar the ecu any way)
Besides if your real clever (or simply work in an electronics store) you can actually do a custom PCB for the Megasquirt that fit's into the Stock ecu casing,, which got me thinking that if everyone was jumping on the wagon (like the ute chop etc ) hen someoe should look into a chip for the sierra (ie pretty much what MS does but slot it in to a standard mazda ecu .. i'm certain i can do this, deends if 1. i can get hold of a blank chip and 2. work outthe software )
€I'm not all talk here but i'm just doing prelimanary theory

He had it running with a carb so we know the engine runs. The only unknowns are injectors, sensors etc, and testing those with a Megasquirt setup is a lot easier than with a stock vehicle ECU setup. Eg, your coolant sensor is working intermittantly. On the Megasquirt you will see this right there on the screen when you plug it into your laptop. Try doing that with a stock ECU. Troubleshooting & setup is a bunch easier when you have information as to what is going on. Additionally, you should be able to get a base fuel map from someone on the Megasquirt board (I have only seen 1.6 guys on there but they will work for a base map).
And to add to that he canuse the bits he already got from the wrecker! Add AU$260 for the Megasquirt & you have a programmable ECU. Mind you, I think it will work if he just throws the stock Mazda setup on there. It wont be optimised for that engine (which you could do with the Megasquirt) but it should work and will more than likely be a million times better than any carb.

Have you ever seen the Megasquirt PCB? It would be a real PITA to recreate on a breadboard. And even then it wont be as reliable as a mass produced PCB. On top of that getting support for it will be difficult too. I have seen pics of a few Megasquirts installed into stock ECU cases. And even if you cant get it into a stock ECU case who cares? As long as it is in a case.
Chipping another ECU is not a bad idea but 1)You need to get someone to do it, and 2)It is not tunable, so it only really works properly on the exact engine it was tuned for. A Megasquirt has none of these drawbacks.
Sorry to sound like a late night informercial for Megasquirt but to me it seems like a great solution.
10mm alloy Both the brass tits from under the plate run water from the manafold through the throttle body. They are threaded in and liquid welded. Will make a braket for the throttle cable tomorw. Then its down to suziworx for him to sort out those wires.
