better pic than link...


what is considered high engine temp for you guys... I've always fought with warm up/hot start with my CHT sensor clamped on # 3 head...

Hey Phillip

Here is a pic of RSR clips. They measure
3”x1”.

Where did you get yours? I bought a set from over (some user manufactured those) here a year ago but they never came to me.

Hi All

I am having an issue with my Tach not matching Tuner Studio. The Dash is approximately 300 rpm higher than TunerStudio Over the last month I have been redoing some of my wiring while adding the Perfect Tuning CAN Gauge. I did not change any of the Tach wiring from last fall. I did try to adjust the Tach Output setting in TunerStudio, but the tach read only about 400 rpm. It was weird.
Any thoughts on trouble shooting.

[jpilcher]

I will try the attached post.

I ended up setting my tacho adjustment to 92%. My tach reading was not linear compared to TS. So, my tach reads a little high at low RPM's but is on the money @6000+ RPM's. My idle is about 950 - 990 in TS, but tach says 1100 RPM's. My tach has a lot of dampening in it since I had it rebuilt several years ago so it does not see little variations the TS shows.

Thanks Dennis, 88% seems pretty close for idle. I haven't had a chance to get out on the road yet.

[jpnovak]

The factory tachs are usually high compared to TS.

Actually, the factory tach reads high compared to my timing light and a few other sampling tools off the ignition. Likely difference in capacitance of the timing circuits that interpret the signals.

Hi Guys

I would like for MS3 to control when my oil cooler comes on. I currently have it controlled using a manual switch. I re-purposed the rear wiper switch. It's essentially completing the ground circuit for the fan.

I was planning on using one of the MS3 Hi-Current Out wires to control the fan. Do I need to run this through a relay? or can I hook it directly to the ground wire on the fan. The original fan circuit is already fused and powered.

Is anyone else doing this? If so how did you accomplish this?

Thanks

John

[smurfbus]

Not sure but if the high current outputs provide 12V or ground. I used one of the extra injector wires to ground the WMI relay.

[jpilcher]

It's a ground output.

* whether they had the firepower to support serious cylinder pressure -- so far, we've done over 125hp/cylinder without a problem. A drag car on the dyno did 44psi, no spark issues.
We settled on a Toyota/Lexus-application COP that is easily supporting 125+hp/cylinder. We were blown away when we saw a 4-cylinder Time Attack car on the dyno run 45psi boost with these COPs and have no ignition issues.
They fit quite securely, or you can restrain with the old RSR-style hold-down tabs if desired.








Yes, have done that before.
Which sensor do you have -- or do you need one, too?
Last job we did with machining + sensor + connector was $245.

what COPs do you use.

As i`ve had tons of trouble along the way i actually drove it for the first time in years today. It was horrible!

I got the car running full sequential on high idle but smooth. Touch of the pedal it was responsive and willing. But, i had an oil leak that took fire on the header from the chain box gasket/o-ring. Did a repair keeping the cam steady and replaced to same position. But after first startup the ms3pro gave me cam fault and lots of sync errors and would not start unless full throttle. So i thought i messed up the timing when i put it all together again. So, again, took it all apart for cam timing. Timed the cam (only left side) from around 0.98 lift to approx 0.72 ish. All went perfectly but, same problem with running and apparently no cam signal. So f@ck the cam sensor then. Turned off full sequential and changed to one wheel trigger only crank, and it started but ran like ****. Since then it sounds like it runs on 4 cylinders. No power at all and lean. Tried autotuning in TS but just barely get it moving. I was so dissapointed :cry:

I thought i was ok on idle but it sounds like it has 4 cylinders instead of 6 and it runs like a 10hp vw beetle. Absolutely no power at all and barely able to take off. Can this kind of behavior be related to timing? Sorry to be such a n00b btw :roll:

Got 43psi fuelpressure, seem to have spark and did nothing to anything other than relating to chain box.

I have the Clewett/Electromotive trigger wheel and a bit unsure to offset on angle tooth #1. I`ve set it to 60 degrees. This shouldn`t have changed anyway.

Setup:

3.3 on ms3pro standard 930 intake manifold and cams
bb IC, headers and K27 7006 turbo.
Electromotive/Clewett 60-2 trigger wheel, VR sensor, coils
Siemens 80lb injectors
Front 044 fuelpump running 43psi according to the gauge.

Could i have done something to upset the system by work at the back of engine when timing? I really don`t understand.

Wasted spark and you talked about full seq?

Did you put your plug wires correctly? Easy to mix two and run ****ty.

[smurfbus]

Also report your idle MAP/kpa range. If higher than 60 you have big vacuum leaks. Drop the 900 rpm timing from 60kpa to 30 kpa to 8 to handle bad hunting.

I messed up i see now. Thread is here
