From memory the airflow meter number is 878. What sticker you're missing? You need stock eprom number for your car or you want to find out what ecu you have?I can't tell what airflow meter i got in my RVR, might be a problem to purchase the ecmlink... it seems theres no sticker or model number on thereany idea how to identify it?

Guys
I am back with a little bit findings of my car
I guess I am running on a older 4G63T motor as my car is a 1995 made model
And my ECU model number is MD2426xxx something like this that I need to check again later as I don;t have good tools and guts to pull out the whole ECU
Currently I only run on a simple sub computer Field SFC Hype R to adjust air fuel ratio to around 12:1
I once bought a duplicated mugen chip for my Honda vtec motor for just 10 dollar on on ebay years ago and work impressively
I desperately hope same mod can be done to my Chariot GT as well
That must by very cool!

vr401 - i meant the sticker on top of the mass aif flow meter, its missing. I think if im going to buy the ecmlink lite they will need to know what MAF type im running on my RVR, correct?
ChariotGThk - I think there a few ppls using ecmlink in this forum, umm best advice to check the sponsor forum for ecmlink.

It may be a cable issue. We had a customer a few weeks ago send us an ECU from his RVR. We had sent him a 2G DSM (OBD2, EVO8-style) datalogging cable with his ECMLink package, because our experience with RVR ECUs said they were all OBD2 ECUs. So that's what we sent him.
But, for whatever reason, he could only find a 12-pin ALDL (EVO1-3 style) port in the car. Based on our conversation, I was pretty sure his ECU was OBD2, not OBD1. So he sent it in for confirmation and sure enough, the ECU works with the OBD2 style cable, NOT the older 12-pin OBD1 (ALDL) style.
So why his car only has an OBD1 (ALDL, 12-pin) connector we'll never know. But his ECU was physically compatible with the newer OBD2 cable.
The two cables are electrically incompatible with each other. So if your RVR has a 12-pin connector, you might be trying to use a 12-pin ALDL cable to talk to it with EVOScan which may not be right. It may be doomed to fail simply because the cable is electrically incompatible with your ECU.
I believe that customer I mentioned above plans to simply hardwire in an OBD2 port so he can use a compatible OBD2 cable.
FWIW, other RVR customers of ours have been able to find OBD2 ports in their cars just fine. But apparently some can not. I find that a little strange for sure. Why put a 12-pin ALDL OBD1 port in a car that is only compatible with the 16-pin OBD2 cables? No idea.

I had a good look underneath the driver side HSG RVR 1997. I though the port is on the left, but then I found out it was on the "bottom right inside"... but there's no flash port, do I needs the flash port for ecm link? Can some one confirm that's the 16 pins port OBDII I got there?
No ports on the left side....

Yuh I got informed by Tom, he will need the sizes of my RVR injectors and model of the mass airflow meter.
Any idea where is the model of the MAF meter? I had a look yesterday, there's some indication of peeled off sticker on top of the MAF meter so I presume model number is missing?...
It's the one on right side behind fuse box and it's obd2. Your maf is 878 and injects are 450 auto and 510 manual.

Umm it has yellow injectors, i better have a good look again.
What I was trying to say is that running evo3 eprom on rvr board car will run ok but evoscan will not connect through obd2.
Yellow injectors are 510cc from manal rvr or evo3.

Thanks for those maf compensation vr401... I'm still uncertain of my maf meter is it 878 or not. Please have a look at the pics.

As for the injectors, I found out they are INP-019 MDL 510cc.
spec: 510cc/min @3 bar , low impedance PART NUMBER: inp019 inp-019 mdl-510 according to the following ebay listing.

I wouldn't be worried about afm. Just set it as it is stock 878 from hsg. Latter on when you start tunning with ecm you can fine tune if it needs adjustment.

Yeah...what he said.
Just get it close enough and then you can use the fuel trims to auto-adjust for you.

Thomas,
Could you tell me what do you have in ecm to tune bigger cams in regarding accell and decell enrichment. I have 272 standard lift bc cams installed in my rvr and i had an issue with stalling on deacceleration or of the mark full throtlle would flood it with fuel and car wouldn't move of the mark. I don't have these tables to adjust on my chip so luckily i had safc and i set it somehow not to do that.
Thank you
Miodrag

Stalling on decel is usually caused by disrupted airflow on throttle lift (vented blow off valve, for example, or even just changing the piping between the airflow meter and turbo inlet can do it). We have an "airflow simulation" function for this that usually helps.

I'm having the same issue over here, and im using some unknown chip from the previous owner. The rvr will stall or starts bogging when pushing the clutch down or having the clutch down and hold or free reving; this happen intermittent or else it will working fine all day long. I though something is not right. thank you for pointing out Tom. Will have a look at the page at http://www.ecmtuning.com/wiki/idleair

Is there anything on the cards like this? If so, this'd be awesome! http://www.youtube.com/watch?v=v-4SbWwAbZA Android tablet with realtime feedback and diagnostic readouts. What would be even better... if you could tune with the similar idea via bluetooth. This would make my android tablet all the worth while having!
