Vitara 1.6 8v

[pkagiantas]

So here i am just got a vitara 1.6 8v TBI ( fitted with lpg too ! ) and 3 days in my possession it i already put it on the dyno

made a whopping 50 wheel hp and 89 NM wheel torque
here is a video of the dyno https://fb.watch/eUYox4VTaP/

and the dyno sheet


some days later i it crossed my mind to check the base timing and it was at least 5 degrees retarded


i was wondering if someone has run one with RusEfi yet
i have some proteus units here sitting around
is the dissy trigger patter supported ?

i will take the distributor apart soon just need to find some spare time

the scope of the project is on the photo or to put a 2liter engine on it

is the dissy trigger patter supported ?

What trigger pattern? Need more info

[ELMEPRO]

usually before tuning car we check ignition with timing and check if trigger wheel decoding correctly?!

Who tuned what ?
all i did is throw the car on the Dyno ... plus i tune cars for living so dont worry about it all i asked if ithas been done allready

I haven't took the dizzy apart yet will try to take some photos and a scope on it soon

from what i can understand its an even 4 pulse trigger probably a 5v hall sensor
looks easy to modify and put a 24-1 in and run it as a missing tooth cam speed if this one is not supported

all the wires i scoped tho i couldt get a clean signal maybe my probes are not the best and i might actualy got the tacho signal

also any easy way to drive the injector ?

its a Low z type 8ohms as autodata says

[MHTSOS]

Easiest way is adding a series resistor.

i was under the impression that it needs a peak and hold driver

[MHTSOS]

Ideally you can make a peak n' hold driver with LM1949 but it can also work with a series resistor to bring the total resistance around 12 to 14 ohms. In that case you will have to calculate the injector dead times from scratch. Best solution would be to install a high-z injector that fits in this manifold. That way you will have reliable data about dead times and flow.
If you eventually install that turbo the stock injector will be too small anyways.

cant install a new injector unfortunately its a single point throttle body injector


the idea is to run it as is just to see that everything works
and then fit a saxo fuel rail that seems like it fits and convert it to port injection and slap a turbo on it

[pkagiantas]

setting the trigger type to Mazda SOCH 4
reads rpm on cranking with out sync loss

i havet started the car yet still need to modify the intake to fit the injector rail and make a turbo manifold for it
