Engine
Inline 4 cylinder natually aspirated engine.
Intake
Stock setup is four 39mm flatslide carburetters.
Planned setup is 38mm throttles from a Suzuki GSX-R 600, including the stock injectors.
Note: This is from a GSX-R 1000, but the 600 version is very similar.
Ignition
Stock setup is two coil wasted spark. According to my Haynes manual the primary resistance of the is 1.8 to 2.8 ohms. Would that make it suitable for inductive ignition ? It is CDI based ignition setup.
Second option:
Suzuki GSX-R coil on plug.
According to the Haynes manual the resistance of the primary winding is 0.8 - 1.2 ohms, would that make it suitable for VEMS?
I think it was Jorgen that told me coils lower than 0.5ohms are unsuitable for VEMS.. but I just want to make sure.
There is no simple rule if you can only measure resistance (eg. the old oiltanker types are good for inductive type ignition, despite the high resistance). Knowing the size and/or inductance helps a lot.
- Very small transformers are only good for CDI, which means at least a 350V supply is necessary and a 1uF cap (at the ignition transformer supply rail; instead of +12V). Make sure noone touches the coils when the ignition is on (should not touch anyway, but extremely important for this setup). Consider it experimental (or "hack") with v3.x, the new CDI ignition board is months away. CDI is coming back, because of motorbikes and IonSense
- Bigger transformers work for either CDI or inductive type ignition. This is the more common nowadays (the standard VEMS v3.x setup).
Trigger wheel:
Please elaborate about the rotation of direction. If I think right, the same code that processes the MembersPage/FiatStilo trigger should be able to process this too (triggers on lower than average tooth-distance, instead of the common multitooth setup, that triggers on higher-than-average.)
The engine rotates clockwise, it's a bit hard to see, but there is an arrow indicating the direction (just above the 1222 number on the wheel)
Recent photo of the engine. Two wires run to the pickup coil. VR type sensor.
New trigger wheel:
Either 4-1 or 8-1 multitooth
- another_trigger_tooth=2
- trigger_tooth=0 (there is no other option !!!)
- another_trigger_tooth=4
- trigger_tooth=0..2
As you see, extreme care is needed so the trigger_tooth will be positioned 40..80 crankdegrees (preferrably 45..60 crankdegrees) BTDC. With a 60-2 wheel, it's very easy to select trigger_tooth. A low-toothcount wheel needs thought about positioning when it gets installed.
VEMS
Diagnose plug (rs232), Bulgin - Micro Buccaneer 400 Series.
LCD plug ITT Industries - SureSeal.
Sensors
- TPS. According to the Haynes Suzuki Manual the TPS shold have a resistance of 1.1Kohm when closed and 4.3Kohm when open.
- MAP
- Crank trigger. Almost certain that stock can be used. Most likely VR. (HALL or even optical can be used as well, just find out which type it is: count wires, measure Ohm with DVM, etc..).
- CLT
- IAT
- WBO2
Injectors
According to the Haynes Suzuki Manual the injectors are supposed to have an resistance of 11-16 ohms @ 20C.
- Measured my four injectors to 21-22 ohms. Don't know why they are not within spec of the manual.
- don't worry about it. Likely they are perfect high-impedance injectors.
[MembersPage/PhatBob] I think that we need to have some sort of priority list for the manual.
Triggers: Types (Hall, VR, optical, distributor) and configuration (missing tooth, multi tooth, sync etc)
Sensors: Water, air, tps, map (manifold fitting guide required)
Injectors: High/LowZ
BUG?
When testing with a 4-1 wheel and the DUAL_IGN code it seems that
in some cases the cyl3 coil stays on.
cyl EC36-Pin# IGNOUT
1 35 0
2 24 6
4 33 1
3 10 7
If the last tooth on the wheel end up at the VR sensor it _may_ cause the cyl3 to stay on.
