hi,
i Am new to this list so please excuse the poor terminology i may use and
feel free to correct anything i say.
I am from australia thus the '808 which is similar to the '165, i have a
computer from a holden camira which uses the same ECM as Astra and some
commodores.
I want to use this computer on a Ford 351c engine with 671 supercharger
pushing only small amout of boost. I plan to modify the intake manifold to
except injectors and was hoping to do away with the dizzy in favour of a
distributor less ignition systems. (DIS??)
The problems i face and hopfuly you can help with are:
-Will this ECM do the job i have just described?
- The ECM i purchased came from a distributor car wheres the same ECM is
used on distributor-less igition systems on the VN V6, wheres the same
commodore in V8 went back to distributor. In the FTP section there is some
wireing diagrams of the various ways this computer has been used. I herd
somewhere it is simple to convert distributor to DIS by simply replacing the
6cyl coilpacks and module, with the same set up from a v8 vehicle. Sound
advice except we did not get a DIS V8 with this ecm that i am aware of. i
had a look at the 1227165 manuals but they arnt the best ive seen plus do
not know much between the 165 and 808. I herd once that LT5 Corvette DFI
Coilpaks can be used on v8's that wish to use the 808?? What are my
options?? Has anyone done this before, or is there a "165 DIS that i can
substitute the DFI from???
- Can i simply wire the injectors the same way the V8 808 is wired or would
there be some underlying thing i have missed, (i have been led to believe
the computers on all the vehicles are identical just the chip and loom and
sensors was played with)
- If i do change from Dizy to DIS will the engine still run or would the
chip programming be completly wrong, If the chip is an issue would the
corrections be difficult? In RT cat there is a slide bar which allows you to
change the number of cylinders, would i be best taking a DFI V6 chip and
increasing the cylinders, or correcting the spark table of the V8 chip,
would i even have to correct anything major? Is it possible to use a 165 DFI
chip if one exists??
- Can someone please exlain what what "All use the 1227808 ECM which is
equivilant to Corvette's 1227165, but without U2 (the SXR chip), limiting
them to 160 baud ALDL data." What is baud Data is this the amount of
information a chip can store?? sorry i know this is a real nebie questions.
- Can anyone point me in the right direction for learning all the obious
sort of stuff so i do not have to ask stupid questions, i have had a brief
loook through the archives and am presently reformating them into a more
readable format and hopfuly a search function to be placed on a webpage (if
no one objects) Is there any good reading on theP4 or delco systems to help
me along ??
i have plenty more questions but ill get these sorted first :)
thanks in advance.
