If you just open this box up and tweak that... it does this unless its an 89 model then ya need one of those instead..... AAAARRRGGGHHHH 3: No political sign offs. We are anarchists on the net, and recognize no governments (or physical laws ;-). 4: No hype, the only stuff I want to see on here is discusion of related or bang on topics, with a view to home construction, on a sensible budget. 5: No flaming, or slagging people off, else the perpetrator wont get a chance to be flamed, he will be removed from the list. 6: I'm the boss, what I say goes. 7: Keep coming, and keep em short, reduce the bandwidth. I want to see serious snippage. 8: The whole lot will be archived for future reference by anybody that wants to see it. 9: Take the time to reference your mails subject line, so that threads are easily followed. When the thread wanders off, and has SFA to do with what it started on, change the subject. If ya dont... you know what happens, its public ridicule time. 10: So you got a project, and ya want it on the web, or just a link... shout, we got an WWW sight up too, I'll publish the link to that later. How to get on... send a mail to: ignition-request@xxx.org How to send a mail to the list: ignition@xxx.org My humble thanks go to Simon for setting this up for us.

Hi William, Just to put the record straight the only injectors that that have the flow rate specificed in g/min and g/1000 hube are the injectors that you have picked i.e. 0 280 150 600 to 0 280 150 608, all the rest (injector part Nos 0 280 150 010 to ... 985) have all got their respective flow rates in cm^3/min and cm^3/1000 hube. The only other injectors that have their dynamic flow rate in mm^3/hube are 0 280 150 001 to .... 009. Nominal fuel pressure is not 2.5 bar in all cases, the fuel pressure is specified in kPa. I hope this helps. Before everybody swamps me Email about putting the specs up on the net, I don't thing Bosch will be too happy with me. If you have a part no that you are trying to find the flow rate for, Email me i'll try and help as much as possible.

Face facts, if we knew how to program GM C4s, all our problems would be solved ;-) How about the analog box I opened up and put some pots in for all the calibration points... One day when I actually hook it up I'll report on how if goes. However I think what you've said is generally true.

Any recommendation for a sub. My pu use a small tank with the stock 86 pump inside, so dual tanks could be retained. What year 280zx? Is that an in tank pump? Wondered about mods to the EGR valve itself-changing hole sizes for neg back pressure part? Of coarse software is even easier. I will send my friend out with your parts list-he's good. Forgot to mention, he picked up those part for $50 (lucky dog). Finally John, can you bypass VATS for an 89 prom #16133479 in software also ? If you can, please let me know how to ship you the prom or if will provide how to info. My pu is registered in California-have been to smog ref and passed inspection. There is a sticker in door jam to indicate my TPI is from a 86-prefer not to go back to ref.
