HALP! Tuning newb.
 
So I installed me ms2e I received from Reverent. I have a 2005 msm with intake/downpipe on wg psi.

I installed the 650cc injectors I have and then installed the ms unit. Wired in my wideband. The afr on the gauge matches whats in ts. Ran my vacuum line to the unit. Then followed the steps for setting up my tps. Set the timing to fixed. Set my timing degrees to 10 since there were no special instructions for the msm. Car ran fine on the stock ecu so I would assume timing is ok? I don't have a light to see what it really is.

Rev sent me a 650cc map to load and followed his instructions:
Go to Basic Setup -> Engine constants and setup your injectors/engine in there

Displacement: 1839cc
Cylinders: 4
Injector flow: 650cc
Air-Fuel Ratio: 14.7

Remember to select "CC" and "cc/min" on the right.

Then import the fuel table attached in the VE table 1.

Did all that.

The car starts, but idles high at around 2000rpm. Even when the motor is warmed up.

I checked for vacuum leaks, didnt see anything out of order. My vacuum level on my boost gauge is normal.

Next thing I checked was my throttle cable etc to make sure I put the tb back on correctly. Thats fine.

I played around with the closed loop idle target rpm curve and can't get it to idle below 2000rpms even if i just take the whole curve and set it too 800rpms.

Is there something I'm missing? Anything else I can check? Is there a way to adjust idle I'm missing?

I'm a complete newb to this and am just getting acquainted with the interface so forgive me if I sound dumb lol.

Thanks in advance.

target rpm is just the beginning.

tell us about the rest of your idle settings

Mazduh 06-24-2013 10:55 PM

Well I would but can't till tomorrow since a random storm came through and knocked down a power line in my backyard. Blehhh now I have no power and laptop is dead. I shall see if i can get that info for you in the morning. What all should I look up? Again sorry newb.

Look at base tunes for a 99 or pretty much any 1.8 the idle settings should give you an idea.

Terrible advice, ignore.

Does the green "CL Idle" indicator light in the lower section of the Tunerstudio screen while idling at 2000rpm?

Get a 12 volt to 120 volt converter for ur car. Bought one and definitely worth every penny.

True, don't listen to anything I post at night.

I will double check this shortly.

Houston to Apollo 1: How did you end up with that spark table...













...did you use a table generator?

Ryan_G 06-25-2013 11:40 AM

What is happening with that spark map? Is that using some different measurement or are you really running spark advance near 90?

EDIT: That spark map is so insane that I am surprised your engine did not explode while idling.

18psi 06-25-2013 11:51 AM

OH MYYYYYYY:laugh:

Next time someone says they have an aggressive spark map I'll link them to this thread

I did not knowingly change anything. Only followed instructions so I have no idea how I ended up with that spark map. Whats the best way to correct it? I'll be honest. I don't know what I'm looking at on that table.

For rev:

This is what a spark table should look like and this is still a tad bit aggressive while in boost for a stock engine. You should probably start out with something similar to this but take out a few degrees in all of the cells under boost.

Braineack 06-25-2013 12:13 PM

what's interesting is that you're idling at 10°, but your spark map is demanding 69° at that area... what am i missing here?


post the actual msq.

18psi 06-25-2013 12:14 PM

his ts gauges show 10* at what I'm assuming is him trying to idle it.
so either his timing is locked at 10* or something really weird is happening (assuming rev didn't accidentally send him the unit with that spark table loaded)


***edit:
Scott beat me to it

So is the reason the car is idling so high because of this aggressive ignition table I seemed to have acquired? Sorry just trying to understand.

Sorry again, where do I find this? I'll gladly post it. lol

BTW Car is just idling. I've not even hit the gas at all yet too scared too.

18psi 06-25-2013 12:17 PM

If you're seriously that clueless, I highly urge you to take it to someone that knows what they're doing.

Seriously.

On a level of readiness to tune a full on standalone between 1 and 10 you are a -70

Awesome. Will do. I have a buddy who knows what he's actually doing. I'll just wait till he can make the trip over to look at it. Thanks for the help so far guys!
