So after reading certain threads and people talk about different stages and what you need, I decided to upload Stage 2 maps on my Procede. You can really feel a difference between Stage 1 and 2. I have my car completely stock and is running great. I only use 93 octane(Shell, BP or Exxon) and the weather here has been less than 40°F.

Most people are comparing the JB3 2.0 vs. Procede 4.
Map 3 = Stage-1
Map 5 = Stage-2
Map 7 = Stage-3

I've been reading that people are running JB3-Map 5 just fine completely stock with the the same temperatures. Since I'm a Procede user, I decided to upload Stage-2 on my car and notice a big difference in power delivery when driving. I'm running the latest 2-10 maps and firmware with no problems.

I'll do some data-logging later this week when it stops raining. I don't want to go back to Stage 1 after noticing the difference with Stage 2 when it gets warmer. Anybody here with the same situation?

I used to run stage 2 with absolutely no problems on my car with just dci (before I got meth). The datalogs looked great and I decided never to turn back

[Glowin]

The proof will be in whether you have timing drops or not I guess b/w 4000 RPM and 6500.

Let us know. I'm curious too.

[Sniz]

curious when the temps pick back up as well, might have to adjust

Yup.....I was having boost oscillations on the early beta stage 1 maps and couldn't seem to get rid of it.

So I tried the stage 2 map as part of a troubleshooting process and found it was not only noticeably stronger than stage 1 (around +1 psi more boost), but the oscillations all but disappeared on the stage 2 map.

Given I am only running DCI and 94 octane with 33F ambients, I dialed UT down to 96% and retarded timing a bit.

Initial stage 2 datalogs showed an occasional timing drop of about 3 degrees between 4-5K rpms so that is why I dialed it down just a touch.

So far the car is running great!

Datalogs are your friend!

The amazing part for me is that the car does not feel artificially over-boosted.....it just rips like a normally aspirated engine.

What's the peak boost for V4 stage 2?

From reading (http://www.vishnutuningforum.com/for...read.php?t=990) it's 14-15psi. Don't know if this applies to v4 though.

Yeah, my data logging last night on this definitely coincides with those values. I was seeing a max boost pressure of 14.9 psi on stage 2. I'm at 5280 feet as well.

Sure feels strong!

Mine peaks a little over 15 psi on most runs.......averages high 14's to mid 15's throughout the powerband.

The shift spike can hit between 17-19 psi

Just to clarify, that shift spike is on an 6at. You can adjust the amount if spike by adjusting your upshift softening. Typically, I like to keep it 2-2.5psi above max in-gear boost target.

None of this applies to 6mt cars as they do not see any shift spike.

Shiv

So increasing the upshift softening value above the default value (which I think is around 30% or so) will serve to reduce the shift spike accordingly?

Or to put it another way....going UP with the value will make the spike go DOWN.

Correct... increasing upshift softening will reduce the mid-shift spike. Decreasing will increase the spike.

Shiv, What are your thoughts on running stage 2 with just dci? I noticed that stage 2 is dci and completely catless... that seems to be a large discrepancy in modifications to be able to run map 2 (or even map 2+) without the supporting mods. would running the extra 1 psi in stage 2 maps be worth it if you're just going to take away timing with user adjustables?

I logged a similar combination and got a saw-tooth (bad) timing curve from 2500 to 6500 RPM.
car: stock 6MT
Firmware: Pro4v005
Map 2+
Ign: 100, UserTq: 100
Fuel: 93 oct
Temp: 36F
Boost: manifold gauge showed 14.5 PSI at sea-level

I'll try it at UT: 80, but I'll likely go back to Map 1+

[vase330]

Stage 2 Maps too aggressive for completely stock cars IMO. I would never buy one of these cars used that's for sure. You have no idea how much abuse the car endured already.

[lacartus]

Logged Map1+ from 2500 to 6500 RPM.
car: stock 6MT
Firmware: Pro4v005
Map 1+
Ign: 100, UserTq: 85
Fuel: 93 oct
Temp: 36F
Boost: manifold gauge showed 13.5 PSI at sea-level

The timing curve is smooth after one run, but gets a step (timing pull) if the next run is done within minutes...cooling down and step goes away.

For this combination of car/environment/fuel I would recommend 1+ at UT 85%, the Map2+ is relying too much on the DME to pull timing.

All of that said, the Pro4v005 firmware & map1+ build boost noticeably faster than the Pro4v003 (10-Feb IIRC)

That's why an intercooler makes so much sense......the heatsoak factor can induce timing pull.

I'm running stage 2 at 95% UT and 105% ignition correction......in essence a detuned stage 2 on a mostly stock setup.

When I run 100% defaults I only get a single timing pull event - you seem to be getting multiple events within one gear.

So not every car is the same even with similar mods or lack thereof.

That's why datalogging is so crucial to finding where your car is comfortable.

Speaking of which....I will be reinstalling my aftermarket intercooler soon which should help to keep timing advancing in the right direction and intake temps about 30 degrees lower.

As it stands now, with 30F ambients, I am hitting about 90F intake temps by the end of a 3rd gear pull.

The timing events seem to occur when intake temps hit around 80 to 90F.

[FotiosF90M5]

Im running stage 2 and its running incredible. Im still playing around with the settings to see how well the car is doing. On my particular car its looking good. It looked pretty good even with ign correction at 50%. every car is a bit different. strange but true. 93 oct and dci. This will all change once the ambient temp goes up. Im getting an fmic next.

[vase330]

You are also right up there by our Canadian friends so you are cold than just about everyone else on here. Any noticeable difference between 50% and 75% Ign setting? Just curious.

not really TBO. it runs good on both. 93 octane helps a bit too. I have one map at 90% UT and 75% ign correction and it seems to have a bit quicker response but not quite as powerful after 4k.

[alextremo]

What is the UT setting for a Stage 2 map to equal the boost of Stage 1? Also - have you guys been able to drop your Ignition Correction to 0 before moving to Stage 2?

Per the custom tuning guide:

Generally speaking, the higher octane you run, the lower the allowable Ignition Correction % you will be able to run and the more power your car will make. In fact, if you run high octane race gas, you will likely find yourself able to drop the value to zero and still not see any “drop outs” in your test logs. This will result in considerable power gains. At that point, you can make the tune even stronger/more aggressive by raising boost (User Torque %). However, this will have an impact on things like intake temperature, heat soak tendency and turbo longevity. None of this is an issue if you are looking to drag race your car for 11-12 seconds at a time. But a much-higher-than-default User Torque % for daily driving (or worse, road racing) is going to take its toll on your car’s hardware. This is why it is better to maximize your tune in terms of ignition advance mapping instead of simply raising your boost. Not only will your car be more drivable and responsive, it will also be safer-running and achieve better fuel economy.

Here you go. The last couple of days been nice. I have two runs on top of each other. The 1st run is in black and the 2nd run is in blue. Please let me know which one is acting better on my car.
This is Stage 2:
