today i was installing manifold i made and turbo oil lines, it start up but rev it up , rev like shit, im assume i will have to tune it but i did think it shuold rev better. i have to install IC+piping yet and make downpipe and dumptube.
please check two maps (one i made and the another guy, a guy from here just made it for me).
im using Nissan T28 turbo with 460 RX7 injectors., stock engine DOHC ZC.
i will have to make a wideband ,i know.

I assume you use crome? Why did you disable everything in the option tab?
Where did you take the basemap? I looked at a map for a ZC in turboedit and value for timing are off by 4-5 degree...

my stock car doesnt have stock lamda (that car didnt came with o2 sensor).
a guy from PGMFI.org sent me DOHC ZC stock map..
btw, i have a question about my turbo, ive heard all turbochargers with open downpipe and they "whistle" a lot, but if you watch second vid, my turbo doesnt do it.. it's very weird, or that could me normal¿?
map i made, just retard 1*/psi and add 120% fuel efficient..
this is stock map guy sent to me.
Im using Crome 1.5.

that is converted to OBD1?
The motor sounds okay the way it is, finish the turbo install and tune the car, don't forget to set the dizzy with the timing light.
You're running a stock flywheel, correct?

yeah, tomorrow ill tune dizzy with my timing light, yes, stock flywheel..
what about turbo sound?
-
does it spin at idle or when you apply a little bit of throttle? You don't even have a down pipe which makes your exhaust super loud over the whistle (if any) that the turbo creates.
Every turbo is different, having a turbo whistling is something i wouldn't worry about. Put the whole exhaust on, tune the car and you're good.
BTW: nice ZC you go there.

Check the timing in the map you made, it is not the same as the stock map.
Non-boost timing should not change over stock.
I looked on google for the name of your map and I found it was for a D16A9.
Look at this one instead http://mycomputerninja.com/~jon/www.pgmfi.org/twiki/pub/Library/EcuDefinitionCodes/P29-T01-321MCU.bin (http://mycomputerninja.com/~jon/www.pgmfi.org/twiki/pub/Library/EcuDefinitionCodes/P29-T01-321MCU.bin)
My turbo doesnt spin at idle too, I don't see the difference at 5000rpm :P
So use the map in the link, don't change timing in non-boosted zone and do what you did with the bin you made for injector scale and boost timing retard.

OK! thx guys ill try that today !! :yes:

I have good luck using this for basemaps on obd1 zc's.

Might want to start at a higher boost fuel %. Like say 175%. Start a bit rich and tune from there.
EDIT: You would have to disable the o2 sensor in this rom if you dont have one.
