#1 123 Dissy with Bluetooth

Post by jagwit » Thu Mar 15, 2018 12:25 pm

Has anyone tried this? SNG 123 BT dissy

Can one actually program the timing curve yourself or does it only offer a choice from pre-programmed curves?
Best Regards

Yeah I’ve got one. You can program the exact curve you want including the vacuumed advance. You can also adjust the timing on the run. A great feature to help get it rite. You have an app that gives you a dashboard with rpm, ignition timings, vacuumed, engine temp, volts, coil current and gps speed. A very useful tool. You can also imobalise the ignition with the app too.

I found the user manual and even the vacuum advance curve is also programmable. This means that it has a manifold pressure sensor built into the dissy and can thus implement electronic vacuum advance as well. It also has a built-in anti theft function as well as programmable rev limiter.

I like this product VERY much.

PS: Apologies JR, only read your post after posting mine.

Built in anti theft program. So your car will only work with your phone in your pocket?

Flaming excellent idea.

It sounds brilliant.

I have bought one but not fitted it yet. I did worry that if my phone goes flat or I lose it I may not be able to switch my car back on?!!?!

Surely its a feature that can be switched on or off (disable thw feature - not the car)

I cant remember the last time I ventured out into the real world without a charged phone in my pocket. How times have changed.

Well I think it the 123 bluetooth is a great idea. I have been driving a Tesla Model S since 2014 and I never think about keys. I just walk up to the car, get in and go as the car knows the key is in my pocket.

By contrast, I also have a 5 series BMW with the worst designed key system you can imagine. Although it is keyless, you never know whether the car is on or off as it has a silly starting button. This has caused loads of issues over the last few years. Where as the Tesla just turns itself off when you walk away from it, the BMW gets you in a right pickle. It might be on, or it might be off. It might be locked, it might be unlocked. The BMW will also grab your phone signal from 100m so you had better be careful if your phone is paired!

I purchased a Bluetooth switch recently on ebay for £20. It detects a specific bluetooth signal (proximity of your phone), then it activates a relay in the same board, switching higher current electricity to your cars fuse box. You can fit in anywhere in the car, even in the bulkhead I suppose.

Fantastic I thought, the thieves would have to bypass it to get ignition on. I never fitted it though. This distributor would save all the agro.

I should provide some feedback on this thread.

I purchased and installed one of these for the 4.2 S1 I've been helping a friend with. And I am highly pleased with the results!!

The car now starts by pressing the starter button and releasing it before you can actually hear that the engine is running, as you would normally say "On, off", that is how quick you press and release the button and she runs.

I've been playing around with curves and at one point I had the engine so responsive that it would best be described as "highly strung", so responsive (sporty) that I knew the owner (in his 70's) would not like it like that. I found myself having to DETUNE the engine so that it would have a more docile nature below 2000 rpm but thereafter I gave it all she's got.

I also found the carbs were not balanced and the mixtures were ridiculously rich on one carb and too lean on another. Once I had this sorted, she runs like a Swiss watch .

We took her out on an extended run over the weekend and the owner could not stop raving about how "the car is going better than ever in 25 years of ownership". He also kept on complaining about the lack of an overdrive gear!

Checking timing with a timing light shows spark at idle ROCK STEADY and 100% stable.

I attach the two curves she is running with at the moment but NOTE: This is running at 1450m AMSL (4750'), so I would expect lesser figures on the centrifugal advance curve where the car is closer to sea level. MAP advance might be very similar. These curves are thumb sucked by moi, and i'm sure one can do even better by tuning on a dyno.

This is the centrifugal advance curve. Note the upwards kink at 2000rpm.

This is the vacuum advance curve. I have found with most of my EFI projects that engines with lower compression ratios are highly tolerant of "aggressive" vacuum advance, which is in part why I have this shape.
