If it doesn't have an eprom then it won't be chippable.
What is the number on the case of the ecu say?

Open the ecu up and take a photo and we will be able to tell you if it has an eprom or not.

I'm sure you know what an EPROM looks like but I have one of those ECU's right here and it has an EPROM. :confused:
On the cover under the "MD150427" there should be another number, if it starts with "E" you should be ok.......or just take a pic. :P

Make a wanted to buy thread Dave. ;)
Should do one for the gearbox as well.

Still can't believe your ECU is Non-EPROM, it even had "E" on the cover. :confused:

my car is an 89 j-spec import, with chipped ecu. pain in the ass to guess where the fuses are cause the directions are all in japanese. back to the point i have an safc2 with 510's upgraded fuel pump + reg, evo 3 manifold and afm. dose this mean i should have no probs with a 20g at 20psi with a new intercooler and plumbing?

Dunno, I reckon it would be running it a bit close. I have seen 76% on my 510cc injectors at around 17 psi on a big 16G. Bare in mind that 17psi on a 20g would be flowing more air and therefore need more fuel.

you should probably upgrade the injectors and the fuel pump as well as the fuel filter, I have heard the stocko is a BIG flow restrictor.
