Re: SECU-3 Lite ignition control unit
Hello, I would like to use SECU-3 Lite unit to run Tatra V8 engine with eight pole VR sensor in distributor. (distributor with cancelled centrifugal and pneumatic advance regulator).
Please do you think its possible ? As I tried to check firmware and I found only Hall sensor version of distributor.
I would like to use dwell control as well.
Thank you
Strecek

Re: SECU-3 Lite ignition control unit
Yes, it possible. You should connect your VR sensor to CKPSx inputs and use firmware for Hall (and use high voltage distributor). Also, you may need to solder 100k instead of default 470k (resistor R32). It may be necessary if your sensor is too sensitive.Strecek wrote:Hello, I would like to use SECU-3 Lite unit to run Tatra V8 engine with eight pole VR sensor in distributor.

Re: SECU-3 Lite ignition control unit
Hello!
I'm looking to convert Nissan SR20DE engine to carburetors.
Do you have any experience with Nissan CAS optical sensor which is located in distributor?
Could SECU-3 use its position signal?
Various trigger wheels can be used. For example:

Re: SECU-3 Lite ignition control unit
It doesn't matter which type of sensor used - VR, Hall, Optical. The configuration of trigger wheel is important. Trigger wheel shown on the picture has 2 sequences of 12-1 teeth and 1 gap for determination of 1-st cylinder for full sequential operation (2 sensors).
SECU-3 firmware should work with mentioned trigger wheel, but note that SECU-3 Lite has only 2 ignition outputs and you can't use full sequential ignition on 4-cylinder engine. You can either use SECU-3 Lite in semi-sequential mode or switch to use SECU-3T if you want full sequential. For semi-sequential operation one sensor is enough (reading of 12-1 sequences).
