Almost makes the case to go back to fuel injection (IMG:style_emoticons/default/poke.gif) ... (IMG:style_emoticons/default/laugh.gif)


Trying to get the carbs to work seemed the cheaper option in my case... but I'm not sure that will turn out to be true in the long run.

Aftermarket dual throttle body FI $ is going to make your head explode. (IMG:style_emoticons/default/blowup.gif) better make sure the cam in your engine supports fuel injection before you step over the cliff. You can tame the carbs for a lot less.

Kevin, your comment is so true, and it's only for a lack of market (I do suppose) that a kit has not been created (to the best of my limited knowledge) for T1&4 engines. When I see some members here struggle to assemble/debug their aftermarket systems, it keeps me from taking the plunge (well, that, and the aforementioned $$ issue). Is there such a thing? I see Micro/Mega,SDI, maybe another out there, but as far as I can tell, there's no true soup to nuts, bolt on plug and play system out there...

I had to pass on the 123 group buy, I'd been wanting to start a thread on the satisfaction quotient for those who purchased them, but likewise, it seems that all bugs have not been worked out as yet. (IMG:style_emoticons/default/confused24.gif)

I'm very happy with mine at this point. My "bugs" were primarily from confusion about which advance curve to select. This was partly because my D-Jet setup was a little cobbled together previously (my original dizzy wasn't correct for my car, which I didn't even know at the time). I wouldn't hesitate to recommend it for someone who's looking at this product for their teener...

Best replacement for the oem dizzy. I've been running mine well over a year now and its flawless. D-Jet 2056. Late model

I haven't heard of any bugs with it. I'm pretty excited about its advantages over the 009 it replaced in my car.

Michael, I wasn't inferring bugs with the units themselves, just figuring out what curves to use. The Bluetooth is an awesome setup.

Are you satisfied with it's performance? I've got a 205A (I believe) dizzy and I'm sure it's the last foible in my tuning process... (IMG:style_emoticons/default/dry.gif)

FWIW. That '205' can be misleading. Looking at the handy AA catalog, if your complete # is 039 905 '205A' that is for a 2.0 engine. Djet. A better dist for carbs is 022 905 205AB. Ljet.

After running mine for awhile I noticed a few things. 2.0 FI. Car used to stumble when cold starting. It would start, start to increase rpm, hiccup and would stall if I did not goose the throttle a bit. Now it does not do that at all.

Idle seems a bit higher (I have yet to actually set the timing as it runs so good I am just going with it till I get a little more time to play around). I will likely adjust idle down a bit for now and really set it in summer when it 100+ again. In the past when at top of the heat range it would drop the idle very low and want to stall. Which meant idle at cold start was pretty high to over adjust for that. I suspect that will go away once all dialed in now too.

Pulls very good. Pulls higher into the rpm range with less effort.

So far very happy. (IMG:style_emoticons/default/beerchug.gif)

No bugs.....no points....no problems so far....I have driven the snot out of my car since I have installed it....even it over 100 degree temps. My car is bone stock D.jet.

Wish I put it on the dyno before and after...but mine seems to pull faster as well into the higher rpm range.

Are the 123 internals as delicate as the pertronix and like setups or the even the
Mallorys?

You mean like leaving the key on due to Alheimers forgiving to see if the electeonics burns up?

Haven.t developed it yet. Just in case I kept thenstock dizzy in tje car for now.

I don't think the 123 has a burn up problem if you leave the key on with out the engine running like the Pertronix and such. They make no mention of this anywhere.

I'll have to check on that Kevin. I am running Ljet on a 2056 with a 9550 cam. I would like, no, really like to eliminate the pinging under hard acceleration at higher rpms.

This way, I could completely put my foot in it whenever... (IMG:style_emoticons/default/biggrin.gif)

In case anyone's curious, here's how we got a manifold vacuum signal to the 123. The T on the left going down through the tin leads to my mechanical vacuum gauge on the dash (which came with the car). On the mechanical vacuum gauge the reading was a bit bumpy (even using two cylinders), but the 123 software seems to know how to dampen this (e.g. a low-pass filter), as it showed a steady signal in the 123 Tune app.

I'll probably add an inline fuel filter to smooth out the signal on my vacuum gauge.

Out of curiosity we also tried plugging into the Dellorto's vacuum port. It did indeed act like port vacuum, so not as useful for my purposes as manifold vacuum.

Doing family stuff today, so haven't yet configured a MAP curve.

Since manifold vacuum should go to zero at WOT, vacuum advance should have no impact on WOT performance (such as a dyno run). Vacuum advance should improve part-throttle performance, including drivability and fuel economy (since with the proper advance you need less pedal to cruise at a given speed).

Is anyone having issues with this distributor?

I installed it and it was running beautifully for a short time.
Now it starts and runs fine at first but then has significant issues after driving for a few miles.
It seems like it is cutting out and not firing, this happens for a short time then it is ok for a while.

Prior to installing this there were no issues.

I really like the adjustable advance but it’s basically undrivable in its current condition.

Any ideas?

Do you have the carbed version or D-jet?


I have D-jet and I just got done with a drive....it has been running flawlessly.

My quess is that it is something else.
