Wonder if anyone can help. I have a jap 92 TT. I bought from a guy who owned it 5 years, but knew very little about it technically. It was imported with a few mods. HKS drager exh, HKS intake/ HKS Turbo timer/ blitz bovs/ lowered suspension and an electronic gadget called "ACS Air/Flow conditioner system" the brand is "Pivot"- never heard of it.

 

Anyway- the guy had it disconnected, said it was causing some problem (it may have been det'ing- though I don't know) The 2 core cable from it goes to the ECU-. it's been disconnected from the controller unit and the ends twisted together, when I seperate the ends the engine stops.

 

Has anyone any idea what this thing is- ?I've attached a poor photo.

 

On the front of the unit is a power button and an adjuster knob marked "VOL %" it's gradiated -10, -6, 0, +6, +10

 

Also, I opened the ECU and it is socketed but the only label on the chip is an OE Mitsubishi electronics label. there is a hand written ticket on the outside of the ECU marked MC8. Anyone got any idea if this is an aftermarket chip?

 

I'd welcome any help

Thanks

Leonard

Sounds like it is chipped but unless it is a manufacturers name or serial number it is pretty difficult to know what you have!

 

The other device sounds like an AFR, it is a device to adjust air/fuel ratios and will give you detonation unless it is setup properly.

if it is a AFR it will be set up for Japanese fuel, or unless reprogrammed. I would get that checked out.

Thanks for the replies,

Do you know where I can have the chip/ ECU "Read" to find out what it's set-up for etc?

Also- what is the purpose of the ACS unit (I assume it does a similar job to an apxi AFR for example- I don't know what that does either !)

 

Thanks for your help

It is difficult to get anyone to read a chip and see what you have, my advice is to get a chip from John dixon and he might want to read your old one for reference?
