Re: AE86 MAP sensor values

Looks like you got good values. By way of comparison here is a generic old school Toyota MAP sensor graph that I pulled from Toyota Autoshop.

Re: AE86 MAP sensor values

I don't remember ever seeing any specific values for the AE86 MAP sensor. When I used the factory sensor on an aftermarket ECU the calibration was basically connect the sensor to the ECU and power it up. Learn the sensor value at 100kPa(abs) and then pull a vacuum on the sensor to say 25kPa(abs) and...

I want to rotate more but can not. Any ideas. Any one had this problem. You could try pulling the distributor and retarding (?) it one tooth.

Mechanically there is no problem. Just drop the new cams in, check the valve clearances, set the cam timing and you are good to go.

Sounds like the oil temp is just floating as it would in an engine with no oil cooler.

Re: 20v Blacktop oil temperature high with cooler

If you are reading the oil temp close to where it leaves the block, then 100-110degC is optimum,
Under race conditions decent synthetic oil can handle 115-120degC for short periods, but you will
need to change your oil more often.

Re: camshaft fitment

I believe that they are on the TVIS engines, so you could run two exhaust cams if you were short of an intake cam. The knock pin may be in the wrong place to use the back plate timing marks for the intake side, so you might have to set the intake side cam using a timing wheel and dial indicator. Che...
