Hi All,

Squirting a 68 Chevelle and adding a TPI system to the 307. I've looked at the VW and Ford External pumps but would like to find an in-tank pump that will fit in the smallish opening in the stock 68 fuel tank. Rigging it up to the pickup won't be much of a problem, but it has to fit thru ...

Hmmm, OK, I'll give that a try, although VR- is definitely going to ground right now.

Are there no proceedures for adjusting the 2 pots on the V3 board?

Hi All,

We are working on a Toyota Silvertop 4AGE using MSII and the V3.0 board. The NE VR signal is being fed to the MSII thru factory coax from the distributor which has had all but 4 of the NE wheel teeth ground off. The factory coil is being directly driven from MSII.

Initial timing was set to ...

Well, I woke up this morning knowing why my output seemed so crazy. Somehow, in all my messing around, the output that I was using on the LC-1 got reset back to it's default of emulating a narrow band sensor. Duh! I hate it when I do stoop things like that.

I'm going to re-wire the connector this ...

Wow, Ken, Thanks!

Don't know how I missed that thread - I was searching every combination of names I could think of.....

Looks like I can remove the TIP122 and put back the stuff for the regular Fidle, build the circuit in the proto area on the V3.0 and go.

I don't suppose Radio Shack carries ...

Hi Guys,

Thanks for all the responses. The motor is a Toyota 4AGE 20V silvertop with individual throttle bodies. We are running MSII and V3.0, with the MSII directly driving the original coil. VR input is from the original distributor (dizzy to you guys down under) with all but 4 teeth removed from ...

Hmmmm, it said 14.7 Gasoline last time I looked - haven't touched that one. I'm going to pull it out of the manifold as soon as I get home this evening and do a free air calibration and then watch with logworks to verify it reads 20.9 in air before sticking it back in there.

Hi All,

The Nippondenso 3 wire PWM IAC valve that comes on 4AGE Silvertop Toyota motors does not react when wired up like the description of the Bosch units.

The Center wire goes to 12V, LH wire goes to ground thru 40 ohm 40W resistor, and the RH wire goes to Fidle on the MS with a 1N4001 diode ...

Hi All,

I'm having a problem understanding the mixture readings I'm getting at idle. The LC-1 (both in logworks and in Megatune) says that the mixture is at 11.8-12.6, but my ear says that it is about right - if I decrease the VE entry enough to get the mixture to 13.2, the motor starts to hunt and ...

I'm in the process of setting up IAC1A to control the variable cam advance on a Toyota Silvertop 4AGE and made an interesting discovery. I'm using MSII, V3.0 main board, Megatune V2.5 and firmware V2.34.

After jumpering 1A(JS0) to IAC1A and S12C (which is silkscreened S12 on the TOP of the V3.0 ...
