Mega squirt is ON!

Plus one, I can host anything if you ever need it... xmasta19.com

Oh and mr MB haha, we'll have to see about that

 

[VelocitàPaola]

I'm working on a couple different things with my current map. I'm concentrating on intown crusing, so that the car doesn't buck as much when your off the throttle, My issue anywhere below 3000rpms when it does this around 30-40mph at about 0-5% throttle ('ll look up the map numbers later)

Try this...

hey anyone got any tips on making the car idle, and not surge up and down, I really want to get it done using the stock IAC...but if I have to PWM (pulse width modulator) might be something to look into?

 

[VelocitàPaola]

Um... I'm working on something to take care of that right now... but until then, I'd say your best bet is a simple fast idle valve from an older GM.

 

[XMasta19]

I don't recall having idle surge...

 

[VelocitàPaola]

It's been such a long time since you've had a running 2GNT, I'd be surprised if you remembered anything about MSnS-E at all...

 

[XMasta19]

hahaha...not that I don't have two 420a turbos right here in orlando that I see and play with on a regular basis

Mark actually just got his ms up and running, and Joels car should be back on the road tonight after a blown headgasket prompted a little head work. FYI: Chrysler has once again redesigned the MLS headgasket...it's now a remarkeably sexy 4-layer!!!

Ouch

Rand,

Check to be sure that your tables aren't hunting between frames. The jump of one frame to another at idle may be too much of a transition and it will keep trying to adjust. You may need to "smooth" it out there. Possibly your rpm stagger may need some adjusting.

Food for thought.

Okay, I'll definately check that out...well there goes some tuning cash out the window...I'm gonna go to the track in portland, and see what I can pull out....before I do any major changes. Anyone know anybody GIVING AWAY some 750cc or 790cc injectors

 

[Ajax]

Since we are talking about the megasquirt can a guy install a toggle switch on pin 37 (fuelpump relay) as a theft deferent switch, and hide it somewhere?

 

[VelocitàPaola]

Sure. You could put a switch inline between the pump and the battery, or between MS and the relay, anywhere you like.

 

[InfiniteGSX]

Randy, What numbers were you throwing to the ground before your MSnS install?

I haven't done much tuning... but I'm still going to have a shop to my initial tune. http://www.solid-technology.com/

They Pulled 300whp, and 29mpg out of a Stock Block Turbo Prelude and thats my MAIN goal! After that is just later on in the future. I want the Maximum WHP with the Maximum fuel economy. So I just want them to do my Initial tune to get everything working the best they can. And then I'll save thier setup in a backup on my phone and start doing some tweeks just to test things out.

OK guys another idle issue! I just got my MS1 V3 installed but I cannot get it to idle!! Its getting really anoying bc I cannnot drive my car untill I get it to idle especially when its warm. It idles around 450 rpm and really rich! i unplugged my stock IAC since it still runs of the stock ECU and idles really good but at 1500 RPM so that does not work. How to you get it to idle right? If I have to use the GM idle valve how do I hook that up? Any advice would be great because my car as been sitting for 2 weeks and its almost winter!

 

[BigRand]

hey ajax....try running, some lucas fuel injector cleaner...check the throttle body and make sure it is closed when its supposed to and open all the way when your at WOT.....

after the injector cleaner, I have my base timing roughly around 12.... and now it idles right around 1100-1300

The last thing I need to check is the throttle stop position and adjust it so that it idles a little lower.

 

[Ajax]

BigRand do you run any kinda of idle control valve? If so which one? My injectors should be clean, I have a new set of 1600cc injectors that I need to install but I figured I get it running right first before I install those.

 

[BigRand]

what size injectors are you trying to use right now to get it running...because you'll have to redo the required fuel setup.........currently I am not running a gm fast idle valve, which I was thinking about doing, I've been spending my time and money trying to diagonse a rattling sound when my motor accelerates and the motor torques in the engine bay.

Have you tried adjust the throttle stop screw on the throttle body, thats what I'm going to do next, along with confirming that my throttle plate is closed when the accelerator is off, and that it opens all the way when it opens.......

lastly I"m thinking about picking up a brand new IAC, if I don't go with the fast idle valve (which would involve plugging the iac hole).

Check your transmission roll stop (rear transmission mount). Mine was broken before I ever went turbo.

 

[Ajax]

550's yeah my required fuel is set at 6.1 right now. Just thought of something!, how does the IAC work I mean does it use watertemp? If so from which probe? The small one or the larger probe? Bc I did remove my smaller one to install an aftermarket watertemp gauge bc I though that one only controls the stock cluster gauge? Might that cause it to not idle right?

 

[Ajax]

OK guys I tried something and its working really well dont no if it would cause any long term damage thou. All I did was undid the throttle cable mount plate and pulled my throttle cable a little tighter so that my plate is just opens a little bit and retighten, works like a charm recalibrated my tps im MT and everythign seems to work fine. Is this bad or can I keep going this way? ONe more question, how does the IAC work? I mean if your car is idling does is still suck some air through the air intake or does it come from the IAC (were does it draw its air supply from)? Because I did disconnect my intake pipe initially (before I did the cable) and you can here the engine is sucking air in through the throttle body?!

 

[Locke]

The IAC uses a valve in a galley to bypass air around the throttle plate. If you look at your TB, there is hole just before, and just after the throttle plate, inside and on the bottom of the bore. That is the air galley for the IAC. The ECU commands the valve (actuator and pintle within the IAC) to open and close, allowing air to pass around the throttle plate, to maintain the ECU's desired idle.

 

[BigRand]

well I worked mine out with some good old carb cleaner, in the throttle body and in the IAC holes., fixed a small vaccume leak in my vac box. Eliminated my EGR (that had a crack in the pipe right before the mainifold), and I set the base timing right around 10-12 where it was idling, added some fuel, and I played with the (KPA) scale on the left of the vE table so that it would be more stable during idle.

 

[NewTurboTuner]

Hey Rand ....I just came across this post. The car is making some good power for what is has! I didnt read all the way through, but did you get bigger injectors yet? You Air/Fuel Ratio is very lean! ...Way too lean really. You would have been closer to 300hp with more fuel to burn. Dont run it too hard with that lean mixture cause thats scary lean in my book. I like to see 11.5 all the way across

For the idle issue you can check for boost leaks, and make sure the throtle body is sealed up. I seen car with nasty idle because the TB gasket wasnt sealing right.

good luck maybe I'll see you around sometime

 

[InfiniteGSX]

All this talk of MSnS-E has really urged me to finish my own project. I'm trying to make a PnP harness so the install will be easier for others.

This is what I'm waiting for! I'm soo scared to start a MS install... my car has been dead long enough... when I get my engine and turbo setup built... I want it to go in, start and hopefully run good!

 

[BigRand]

yeah I turned the boost down....to 12 for now, I'm waiting to finish up a few other non motor things, and get retuned from the owner of horsepower connection, we had to stop that one day because it was way too hot, and I wasn't getting enough pulls in the time it was taking.

 

[Slo2gen]

have you noticed any tach spikes at idle? I am getting some but only at idle. No other rpm or load. If I blip the throttle the rpms are fine untill the rpms "settle" then it starts to spike again. I think I am going to try isolating the grounds and cleaning them up and getting a new CKPS.
