[Shotimes] Help with LPM

[Ron Porter]

It's a trade-off....

We either continue the flame topic, or we put up with the same number of
stupid questions about drivability problems that can be solved by pulling
those parts off the car.

FWIW, I had an LPM and the 80mm MAF on my '89 as a part of the BOS package.
It worked fine for me, but Mallinson's car ran the same with the same HP
with a 77MM Pro-M MAF and no LPM.....which I like better with one less part
to go wrong. Plus the addition of the MAF and LPM after I had the other
parts installed gave virtually NO power increase that I could
feel......there was "maybe" a bit over 6K, but no other gain. The dyno
showed power over 6K, but the butt dyno can't feel it (read the HP & Torque
Primer on the FAQ that I wrote years back).

Plus, many of the later models have had "issues" with getting an LPM
calibrated right (Vadim did the original calibration on his '89). It just
ain't worth messin' with......spend the LPM money on suspension or brake
parts, it's a better bang for the buck.

Hopefully someone can fulfill your request.

However, FWIW from the old curmudgeon.....sell the LPM and 80mm MAF. Put the
stock 55mm MAF back on....with the Y-pipe and UDPs the car will run better.
No, don't go via "butt dyno", get on a Dynojet or do 1/4 mile runs.

Opening the secondaries sooner is counterproductive. The idle works fine
without resetting with the UDPs. If you really feel that you need to spend
money on a MAF, go a calibrated Pro-M MAF and forget the LPM.

Now, I am not against LPMs, but I feel that they have their value in heavily
modified cars (Supercharger, turbocharger, big NOS hit, etc), but are a
waste for basic bolt-on cars....it's just one more thing to go wrong, and
gives no appreciable performance gain.

I have a Ted B. LPM which does not work
after proper installation (fan turns on and vehicle will
not start).  He and I are attempting
at this time to determine if it is the LPM or the
computer.  I do not know anyone with a GEN2 MTX
in my area so I am looking for help.

Is there anyone with a GEN2 MTX and currently running
an LPM that would be willing to plug this thing in
and see if it works ?  Keep in mind I have some mods
that he programmed in for me but the thing should still
start the car.

This is what I had it programmed for:
X2J ECU, 80mm MAF, raised idle for UDPs, Y-Pipe,
lower RPM for secondaries to open, 155lph fuel pump.

I will send it to you with some $$ to send it back to me.

Thanks,
