I deleted all my old maps because I did some work to the wiring and some parts changes to my car, anyway I started from scratch, changed the scalars from a p30 map to same numbers as a p28, removed checksum added datalogger+rtp, and added boost tools and fuel tools, adjusted for my 1000cc injectors and started it up. after tweaking I got cranking fuel and post fuel worked out I think but it still wont idle worth crap with 15:1 afr, and its throwing codes 24 and 27, what the fuck are codes 24 and 27? its been awhile since i've done this so maybe i'm forgeting somthing simple? this is starting to piss me off.


cliffnotes: what are codes 24 and 27? and what do they mean?

oh yeah i'm using crome pro, this is on a d16z6 in a 93 del sol.

According to : http://www.zealautowerks.com/ecu_codes.html

are you sure your reading the codes right?

are you getting 2 long lites and 4 short lights then long pause?

[ifly87]

well i click on the CEL: ON button in the live tuning section of crome pro and its telling me



Also what the fuck is the knock retard actually doing? I've never noticed it red like that before?

All I did between last time I ran it and now is reground the wideaband to the thermostat housing. it was running find on another map since then, just now after making this new map the codes come up.

also the screenshot was taken after I shut the car off, thats why the afr is so lean.

check your cell from the data port and see what you get.

The light on the dash is on also

The light on the dash is on also

put a jumper in the two wire plug (not the three wide plug w/ two wires) and with Key on see what the service light does.

No code 2 (except OBD0 PR3 PW0 IIRC), must be two long flashes = 20 ELD.  Has no function, disable.

Code 4 = TDC sensor.  ECU derives base timing from this, if the TDC wire polarities are switched it takes a couple seconds to crank and idle has a stumble because timing is off.  Alternately, bad TDC sensor.  Alternately, bad H1C1 board in the ECU.

Code 7, TPS.

Just guessing you're reading them  wrong.  Get vid if they really are crazy codes, curious.

I have not yer plugged in the jumper to read the flashes, I will do verify it tomorrow. But why would crome tell me those are the codes if they are in fact not?
