CA18DET ECU Information - not anymore

200SXSilviaSavage · Post by **200SXSilviaSavage** » Fri Jun 13, 2008 3:15 pm

Some useful info, thanx. Was wondering if the RB25/20/26 AFM will run on a CA18DET? And also would you have to mod the AFM for it to fit? Does the 300ZX Z32 AFM fit directly or do you have to mod that?

* The Stock Nissan VG30 / VG33 AFM will max out at around 300HP (Engine).

are you talking about the z32 maf here? because im almost sure the z32 maf maxes out at about 500hp..

* Nissan was extremely conservative with regards to timing on the CA18DET the same can been see on the SR20.but not to the same extent.

now what does this mean exactly?

Pink, do you have the stock ignition map for the CA18DET?? I am very interested to see the ingnition map when in Vacuum and low rpm.

* First off the Speed limiter is set at 224KM on all Euro model maps,

do the sa one have that?

The Japanese 8 port model ECU’s (Mec-0012) have very different timing and fuel curves below 4400Rpm to make use of the 8 port butterfly system running close to 13.1 AFR before the switch

do the sa one have that too?

Thanks bunny thats very interesting! I'm having my engine temp sensor sorted as we speak

High load is what exactly, 0.6Bar or 0.8Bar??

Those values are true timing am I correct?? meaning 51degrees is 51degrees BTC??

That is 1 hell of a high timing curve, 40degrees plus is high, I only run 30s. Pink where did you get this info from, just want to know how reliable it is. I am VERY keen to try upping my timing in the low load ranges.

What kind of airflow does the stock MAF max out at?? I am just trying to work out where in that "load" will 0 boost be so I have a reference for my adjustments.
