It's from a japanese engine. Part# 23250-62030 In my experience, the last 5 digits are the important part, so if you list something similar, but the first part of the number is different, I love to hear from you.

I'm not one to trust manufacturer's promotional literature. Is there anyone here that can give me a rough translation of this (Jacobs) system with respect to mfgr's claims "senses when the flame goes out, and restrikes the plug"?

I have had it "ping" just like any other system would, weither at a different level of detonation, I have no way of measuring.

An example is promedit or tuna. I wrote and posted the source code to tuna, which uses a simple text file to describe the locations, sizes, and coversion factors for ECM tables. I posted the source in the hopes that other people could make use of it for their ECM editors. Look on the ftp site for tuna.zip. It's in C, hopefully that's what your friend will use. - --steve The Punisher wrote: > > A friend of mine who is an incredible programmer, has agreed to > write an editor for 747's (maby others later).

DOT 5 may have a higher boiling point, but requires more service, and the fluid is more hygroscopic. Another problem is your system design--it will not work properly with DOT 5 silicone fluid. You can go to a DOT 4 fluid--as it is the same polyglycol base product. Hope this helps.

The 16196344 was also used in the ~88 Chev Celebrity 3.1 V6 multi port inj, I have one ( ECM ) sitting on my desk. It also has a GM reman sticker on it. Many V6 cars of this era were factory converted from MAF to MAP. All of the wireing was there and only required a mamcal swap. The 89 Beretta 2.5L 4 cly is a single point TBI / MAP car, any chance it was a 2.3 Quad 4? Sounds like the 16196344 could be a universal ECM.

I was under the impression, after having read it in some mag, that dot 5 could be substituted in a dot 3 system. The only catch is that the old stuff would have to be COMPLETELY flushed out and cleaned out. The dot 4 is higher maintenence too right? It absorbs more moisture "hydroscopic?" James Ballenger ------------------------------ Date: Mon, 26 Apr 1999 01:52:33 -0500 From: "G. Scott Ponton" Subject: Re: [Off topic] ABS & synthetic brake fluid I work with DOT 5 often when doing restorations etc. It works very well, in particular in vehicles which see limited driving time or severe braking. I have never noticed a problem with loss of pressure or a spongy feel either unless there was air in the system. Last I heard you can't compress a liquid unless it has exceeded it's boiling point and is in a gaseous state. DOT 5 better known as Silicone fluid is not hydroscopic at all. This is why many people use it in their antiques. It doesn't cause the wheel cylinders and the master cylinder to corrode. It is recomended you flush the system. It also works better if you rebuild the cylinders and nearly polish the seal areas as it tends to leak easier than DOT 3 or 4 fluid. It is very hard to keep it from aerating. This is why it is not recommended for ABS systems. When bleeding the system you should not "pump" the brake pedal. Either bleed by using a pressure bleeder or by pushing the pedal to the floor once, releasing the pressure at the cylinder, slowly allow pedal to return, then repeat until all the air has been removed. Very time consuming. Once all the air has been remove check levels often. If the fluid becomes aerated it is very hard to remove the air.
