    vg30 Valve springs in an L series head?

    in Nissan L6 Forum

    Posted

    Howdy gang. Hope everyone is having a nice Monday.

     

    Has anyone here ever used vg30 springs in an L series head? I've not yet match the springs diameter however the info I have found so far tells me that teh vg30 outside spring is 048" longer (2.016) then the stock L series spring (1.968). The inside spring on the vg30 is .030" shorter at 1.736". The L series being 1.766.

     

    My big concern is the length of the outside spring, could .048 be too much for the valve? Could this create enough closing force to drop a valve? 48 thou isn't huge by any means but it's all relative to the topic. To give an idea of size difference we're talking the gap in the average spark plug. So, would it make any difference to the durability of the valve head and stem?

     

    I should also know the installed height of both however I wanted to present this question here since so many before me have built many an L series engine and I thought one of you may have done something like this previously.

     

    Thanks to all who can help.

    programming error, raw chip

    in MegaSquirt

    Posted

    Hi Folks,

    when downloading "megasquirt.19" I get:

    "programming address $FB00.error".

    I then continue to see what the issue is when verifying. Then I get:

    "$FB10 byte in modul is $01, should be $09", and:

    "$FB9F byte in modul is $AE, should be $A6".

     

    how can I correct that? I downloaded the .S19 again from website, erased module, reloaded, got the same error. How do I procede from here?

     

    Thanks much for all the help!

    processor programming question

    in MegaSquirt

    Posted

    Okay, is there a code to program a VIRGIN (not from Megasquirt), blank processor in the board (V2.2)?

    In daubt it though due to the set-up. Would be nice if I don't have to buy the programmer.

    Oh well.

    Please let me know, would you?

    Thanks much again!!

    "configuration question"

    in MegaSquirt

    Posted

    Okay, thanks much,

    I am using version 2.2 MS fuel only for now (basic stuff).

    I am using a DB9 cable (RS232) and have gotten the com all the way onto the board. Now I have to plug in the proc. and load.

    But how do I go about it?

    I was trying to follow each step as per instructions and got stuck.

    Could you instruct me, or point me into the right direction so that I can test it?

    Thanks again!!

    "configuration question"

    in MegaSquirt

    Posted

    This is what it says in the manual:

    On the PC, run PC Configurator. Go into the "Communications" window and select the proper COM port (the "Verify ECU operation" does not operate, so do not be fooled). Exit this screen (back to the main window). Note: If your com port is on COM5, you will notice that the Configurator only offers COM1 through COM4. Modify the configuration file so that the first line says "COM5". (Use Wordpad, Notepad or something similar, be sure to save as a plain text file.) For MegaTune this file is "megatune.cfg".

     

    Where in the heck do I find "PC Configurator"?

     

    "megatune.cfg" is just a 4 liner coming up with "Notepad".

     

    Secondly:

    In the instructions just below the above question it says:

    "On the PC, click the "Runtime/Realtime Display" button, which brings up ... "

    And where would that magic "Runtime/Realtime Display" button be??

    Need some help here.

    Trying for the longest time to find those two things with no luck.

    Thanks much!

    TPS question

    in MegaSquirt

    Posted

    Hi all,

    is there a TPS (pot type) out there that bolts either to a 240SX or even the factory 280 Throttle body where I can use the Bosch style 3-pin connector?

    The 240SX has the pot on the extra pig-tail with that huge tree-pin connector.

    Thanks much!!

    350engine/ 1986 GMC T5 tranny, no speedo

    in Gen I & II Chevy V8 Tech Board

    Posted

    The above combo is in a 73 240. Tranny is a Borg Warner 1352-157.

    The speedo does not work. Person who built it (friend) had died from cancer.

    He did not hook up the speedo. The tranny has two (from what I can see) electrical connections on the drivers side. One further back (I suspect the pulse coder for a speedo?) and one up front (reverse switch??).

    I need help to hook the stock speedo (changing out the electrical in back with something mechanical?).

    Is the front electrical the reverse switch?

    Thanks much!
