PSI3 ECU DATA MONITOR HELP
I have the above monitor, and im unsure of some of the meanings or abbreviations that the monitor reports, I understand the obvious such as 'CT' (Coolant Temp), and 'TH' (Throttle) etc, but what are the other manings, had anyone a manual or PDF of what they mean?
PS, having read some other posts it looks as though PSI3 have now ceased trading. http://tbn0.google.com/images?q=tbn:...SECS_Close.jpg Thanks Rob |
Not having a manual or a unit it'd be easier for you to tell us the abbreviations and then we can put meanings to them. Off top of head, some of the ones I expect you'll see would be
IAM =Ignition Advance Multiplier KC= Knock Correction AFL=Air fuel learning AFC=Air fuel correction TPS=Throttle position sensor EL=Engine Load IT=Ignition Timing EX=Exhaust Gas Temperature BP=Boost Pressure MAP=Manifold absolute pressure What else are you looking for? |
TH 0% I guess throttle
ES 1050 varying but proves to be the rpm RS O MPH again obvious BP 09.8 Psi Boost Pressure OT 1 oC Oil temp? OP 99 Psi Oil Pressure? CT 64 oC Coolant temp? LA 14.5:1 ive no idea BV 14.1 V ive no idea IG 12.0 again no idea KC 0.0 ? ID 2.29 ms ? AF 3.4 g/s ? IN 24 oC ? |

Ive just cranked over the car, baring im mind that the car has a new engine 600 miles ago and tick over at 1000rpm as its still cold, well 64 oC by the time i finished the readings:

Thanks very much for the quick response, does this seem fine,
and if anything is worth keeping any eye on would it be the Knock and Air Fuel? Without the oil temp and pressure senders, the most valuable thing to look at is probably that the mass airflow reads consistently under boost. To be honest though the usefulness of those monitors are a bit limited - as you can't easily see the variation in figures while driving, and they don't datalog so you can't check afterward. Possibly part of the reason why PSi3 aren't around anymore. |
It's damn near impossible, mine is set to Boost 95% of the time.

Keep an occasional eye on the knock correction, yes. It's not really worth paying slavish attention to the AFR as it will change constantly anyway, and provided the ECU is getting the right inputs, the mixture will always be nominally "correct".

just to resurrect this. i have recently aquired one of these for my 99 UK impreza but it doesnt seem to be reading the
LA - Air Fuel mix. AF - MAF i just get No Data :( is this because it cant read them on from my ECU or is it a software issue were id need a later version of the software (which im assuming is nigh on impossible to get hold of now) everything else is there bar the oil temp & pressure as i have no senders for those |

In addition, you have stored max. boost, rpm, speed, coolant temp. I assume you guys bought these second hand from people who lost or threw away, the instruction manual? JohnD |
yep i have the manual and selected them through the display edit mode to display them. but on selecting AF and LA it shows No Data :(
|
if its any help, its a SECS S1003, on startup the version numbers are
"08 08-05-03" "SN12172" it then comes up "WHAT DA FUK" which i find odd lol before showing normal display IT - Intake Temp LA - Lambda Adjustment AF - Air Fuel Mixture all show 'no data' - all other options are displaying correctly |

On checking with the makers it turned out to be for a MINI! Did the unit come from a Subaru the same as yours? JohnD |
yeah i managed to get rid of the daft message last night :) my ignition advance sits at about 12 degree advance at idle?
is there anyone on the site (or elsewhere) that you know of that is still able to re-program them? cheers. |
12deg is right for idle.
When you say "re-program them" do you mean just change the display items? JohnD |

@JohnD - no its just dosent show any display for those 3 parameters. i understand the display and how to set it up
@Splitpin - cheers so thats IT ruled out. so now 2 left! ive been told that the there was different OBD connections for different years so it may just be the case that the OBD connection is not suitable for my model of car. so just need to see what pins read what in the connector. apparently detailed in the user manual |

@Splitpin - cheers so thats IT ruled out. so now 2 left! ive been told that the there was different OBD connections for different years From 99 onwards all Imprezas have the OBD2 compliant DLC16 socket, and up until the point the newage ECUs become CAN-compatible, all use the same electrical interface (and communications) protocol. From 01MY onwards they gain the ability to communicate in native OBD2 mode as well as the manufacturer specific SSM mode (which is the one used by the SECS monitor). so it may just be the case that the OBD connection is not suitable for my model of car. so just need to see what pins read what in the connector. apparently detailed in the user manual The fact that you have it working and reading everything else tells you that you already have the correct data pin. If you didn't it wouldn't work at all. It sounds like you're working on the assumption that trying different pins in the connector will allow your unit to read the two "missing" parameters. I'm afraid it won't. The only other pins that are populated in the DLC plug are grounds and power supplies. If you've already done whatever is necessary in the unit's menu to turn those two data parameters on, but it still can't read them, then the bottom line is that the unit doesn't know how to read them. The only way to make it do so would be to reprogram it, if such a thing were possible. |
Plenty of info there cheers & ok still gettin a bit closer :)
Johns runs version SUBARU 14 290404, mine runs SUBARU 08 080503, so its an earlier version software. there used to be an option to get the software upgraded, so now its a case of finding someone who can update the software possibly. ECutek took over the development of the software after PSI3 so maybe someone there would be able to update it ?? |

See post 6. Simon from Psi3 used to post help on here but not seen any posts for a while since the company folded. I've got a SECS and they can be a bit flakey at the best of times LOL. Also hopeless with analoge output such as boost pressure as it's virtually impossible to read. I'd treat it as a toy and get some "proper" guages :D Shaun |
it is only a toy correct but is good for the ecu fault code reading etc.
yeah id seen simons postings on it but the fact he hasnt been active on the site since 2008, i doubt he'd appreciate a call about it |
Gambit....... too true. Useful for reading codes (current and historic) and it has a re-set ECU function :D

The intake temperature function is a moot point as your UK car doesn't have an intake temp sensor. As above the other two are available in the ECU so sounds like Psi3 didn't know how to read or interpret them at the time your unit was made.
JohnD |
Newage cars have a temp sensor next to the MAF in the same housing... :D

Splitpin.......I know I have asked this on previous threads but I wonder who you really are under the pseudonym LOL
Shaun |
@JohnD - Is your's the later VFD version? mines only the LCD version - so im guessing its a v.early model
@Splitpin - Cheers for all the info on this is much appreciated, at least know i know how it works! still be interested to know if anyone can update the software on them. @Midlife - Cheers for the input also :) |
