Birnie Posted May 7, 2007 Share Posted May 7, 2007 You were asking what it idles at.... about 1080 - 1100 depending on the engine temp Link to comment https://www.sau.com.au/forums/topic/165286-brand-new-z32-afm-problem/page/4/#findComment-3104537 Share on other sites More sharing options...
paulr33 Posted May 7, 2007 Share Posted May 7, 2007 no we mean what is the voltage displayed? MONITOR, 1 CHANNEL, AIRFLOW rev it a few times, does it return to the same value-ish each time ?

Birnie Posted May 8, 2007 Share Posted May 8, 2007 Yes, that's what i meant. Airflow is 1080-1100 when on idle. If i rev it does go back to the same level. Is that a bit high? I wonder if I've soldered the wires incorecctly but i thought it wouldn't work at all if i did that. It's a series II so i had to share the 2 ground signals (from memory) Link to comment https://www.sau.com.au/forums/topic/165286-brand-new-z32-afm-problem/page/4/#findComment-3104773 Share on other sites More sharing options...

What are some of you other guys getting for an Air Flow reading with a working AFM on idle.... Standard or Z32......

Birnie Posted May 10, 2007 Share Posted May 10, 2007 Also, I've been looking around at maybe getting a replacement or still hanging on to the fact that this one is OK and just set up wrong. I saw a unit on the Jap Auctions and looks as if the signal ground (guessing) has it's own 'C' clip that would bolt onto the body for grounding rather than going thru the ECU. Also, that wire was extra long on the Tomei plug which suggests it should be different and had the length to be wired into the chassis. Would this change the behaviour of the signal overall?

Birnie Posted May 10, 2007 Share Posted May 10, 2007 ..and, if peeps are looking at getting one, they are on nengun as a Tomei branded Z32 for $360 delivered. If i get a replacement, i think i will get that one. It's so much freeegan hassle to get around this and i don't wanna risk getting another dodge one. And that is possible as i don't think these other dodge ones were sold to rip people off, just the seller, even reputable sellers, didn't know about this bad batch ??? Anyway, just putting it out there as an option, bit more expensive but only $50 over the cheapest I've seen.

Wogboy Posted May 11, 2007 Share Posted May 11, 2007 URAS said: yeah going rate is about $295RRP. When I priced one here a couple of weeks ago, the Bosch Z32 AFM was actually dearer than the Nissan one by nearly $40.00.

Wogboy Posted May 11, 2007 Share Posted May 11, 2007 Blitz said: Thats correct as its not a genuine Nissan part number - Its a Bosch part number The Bosch Z32 AFM still has the Nissan (JECS) part # on it (22680 30P00 A36-000 N62) and the Bosch part # is on the box (F00E000202).

It's a series II so i had to share the 2 ground signals (from memory) I had a look at datalogit log I took some time ago. My Z32 afm on idle see's 1165mv on average. It never sways more than 10mv either way providing I don't touch the steering or pump the brakes. But it is a 3ltr so it 'may' suck a little more on idle.

Birnie Posted May 12, 2007 Share Posted May 12, 2007 Interesting, I'm gong to try and ground the 'ground' wire to the chassis and see if that makes a difference. Doub;t it but worth a try.

benl1981 Posted May 16, 2007 Share Posted May 16, 2007 Silman is yours ok after the retune? Link to comment https://www.sau.com.au/forums/topic/165286-brand-new-z32-afm-problem/page/4/#findComment-3122839 Share on other sites More sharing options...
silman Posted May 16, 2007 Author Share Posted May 16, 2007 (edited) Yes, I got the dyno done and the replacement Z32 is working fine. Not so happy with the power output though of 200kw non shootout mode. It is a low reading dyno, but I was expecting more power. At 1.3bar it's making 190kw at 5500rpm, but then it just flatlines the power curve. Even at 1.5 bar it gives slightly better mid range, but the same flattening out of the power curve occurs. The boost does not drop off at all with the AVCR, it holds steady to redline. My tuner thinks it's the justjap intercooler I bought, and suggested that I replace it for a thicker ARC item with low pressure loss. The AVCR Duty cycle is at 40% and holds boost steady. Knock count is at 14 W.O.T. with an AFR of 10.0 from 6000rpm to redline. What I have is; Series 1 RB25DET with 1.8mm headgasket. (newly built with 6000km run in) Standard cams Apexi pod filter & Z32 Greddy Inlet Manifold Apexi Cast top mount exhaust manifold Garrett GT30/40 .63 Tial 38mm external wastegate Greddy Type R BOV plummed back Power FC and AVCR 720cc Nismo's. 60x30x76 tube and fin FMIC with 2.5" piping throughout. 3" exhaust from the turbo back. Should I put money towards an ARC intercooler, or should I install a set of 256/264 hks camshafts next? Is the 1.8mm headgasket lowering compression so much that it is effecting the amount of boost I have to run to reach my target of 250kw?

benl1981 Posted May 16, 2007 Share Posted May 16, 2007 Interesting Silman..hope you can get your power sorted out. Im just about to get a jusjap 450x300x76 intercooler.. A lot of people are using their 600x300x76 without probs I believe...

Birnie Posted May 16, 2007 Share Posted May 16, 2007 Well Silman, at least the Z32 is sorted Did you find when you swapped it over and started the engine, it was crap idle and needed an obvious retune, or was it still OK to drive just with more room to move on the verticle axis?

silman Posted May 17, 2007 Author Share Posted May 17, 2007 When I swapped it over, it still drove ok without a retune. I was able to drive a few days around the place before I put it on the dyno. The idle was fine. Link to comment https://www.sau.com.au/forums/topic/165286-brand-new-z32-afm-problem/page/4/#findComment-3125685 Share on other sites More sharing options...
benl1981 Posted May 24, 2007 Share Posted May 24, 2007 Birnie - is you new AFM working well now? Has it been tuned. 1. Is there any comparison Dodgy vs New with regards to volts at idle? 2. Anyway we can tell a bad one before the tuner has almost completed a tune I am getting a new one, making sure it doesn't have the Nissan embossing but not sure what else I can do..
