I have usdm b16a2 swap and the previous owner told me it has a type R ecu, do you think thats whats causing the higher vtec engagement?

Should I put a b16a2 usdm ecu in it?

 

change the oil you could be low on oil also correct me if im wrong!

 

Apprently I have a Type R B17 P73 ECU on a usdm b16a2

 

b17? thats a 92-93 da integra Gsr. What ecu exactly do you have in there? read the stamp on it.

 

also obd1-or obd2? more details would help

 

chipped ECU perhaps?

 

if your to low on oil, vtec wouldn't engage at all.

 

Or it could be that your tachometer is off.

 

Sorry its a B18 Type R ECU, code P73.

Wait what is it suppose to engage at on say a 99 si with an stock b16a2?

Definite possibility.

 

Im preety sure my tach isn't off. Doesn't a b18 TypeR redline at 8400 and vtec engages at 6k?

 

my vtec is supposed pop at 5500, ran my friends chipped type r ecu once, he said vtec pops @ 6

 

I think VTEC is 6 on ITR's. Look here.
