So how do I add this electronic boost control stuff for my MSPNP?
 

Alright guys....I got the connector but i dont even know how to work this thing. The directions on the manual confuse the shit out of me. Anyone that can help please chime in.

do you have the boost solenoid valve?

hook one end to a 12v source. the other to the middle connector of the PNP, Pin 9.

then turn it on with megatune.

go to boost kpa target 1


set the TPS scale, if 89-93 do 0 and 100 only

100% = full boost 0% = wastegate boost.

start low, work high.

I set the lowest rpms to 100% within 200RPM of my target for the fastest possible spoolup.

no solenoid valve yet...so i will report back after i get that. I had no idea how this whole thing worked. Thanks for the help

Just to clarify Scott's post...0 and 100 are the TPS bin values to use, since you don't have a variable TPS in 89-93 cars. The 100%, 0% are max and min DC values in the table. Start with low DC values and work to high DC values. I don't want you to think that the DC table can be 0 and 100 only, and overboost your turbo ;)

ok I now have all the stuff from DIYautotune in front of me....can anyone help me? I do not know what to connect anything to. All i can clearly see is that the connector with all the wires connects to the back of the msPNP but where do the wires go and so forth...any help would be appreciated

install the solenoid where your MBC would go.

so between the turbo and wastegate actuator.

the side with the little filter is the side the faces the actuator.


hook one wire from the solenoid to see +12v. (the blue connector in the engine bay)

the other to the middle connector of the PNP, Pin 9.

then turn it on with megatune.

It's all in the manual. Read it until you get it.
Don't start the project until you fully understand. You risk blowing your shit up.

i read the manual 100 times and this shit is FUCKING confusing. Any help???? only thing i understand is how to connect it to where the MBC originally is.. WHere do all the connectors on the Standalone connect to? this shits confusing man lol

I enabled EBC on my MSPNP two weeks ago and it takes about 2 hours to do. It in not Plug and Play though.

Replace your MBC with the new solenoid making sure that you plumb it in the right way around (there is a thread on here that tells you exactly which side goes to where).

Take the red wire on the solenoid and join it to a 12V switched power source. I used the cable running to the blue connector which you use to hook a timing light onto when setting the timing. Mine is a UK car so it is on my passenger side forward of the suspension under the bonnet (hood).

Take the black wire and extend it using some extra cable back and through the firewall and connect it to the wire running to pin 9 on the new (thanks again DIYAutotune) middle connector on your MSPNP.

You should solder and use heat shrink to make sure these joins are strong and secure and use cable ties to make sure the cables don't flap about

Then it just a case of following Jerry's intructions on enabling EBC and slowly bringing your boost levels up.

It helped my car bring boost on quicker and hold it longer. A very noticable improvement.

UPDATE***** Hooked up everything according to the instructions. Havent adjusted anything yet BUT when I go to the advanced menu...i cant click on any of the boost menus. Only way I can go to the boost menus is by going to "REVIEW MODE" where it goes through all the menus...any advice?

go to:

Basic Setting > codebased ouputs

change JS2 = boost control.

scott thnx dude I'll try that when I get home.

Alright folks that worked out fine and the boost tables and such are all working now. Now who can give me advice how to make this thing boost about 14 psi. I have no idea what to do to the tables any advice will be appreciated. I see that 1 psi= 6.895 kpa but thats all i know soo far and 100kpa=1 bar. So I would need like 96.53kpa

:rofl:

100kPa = 0 vac / 0 boost


start with low DC% start at 20%, work your way up untill you hit your target, then tune the boost onset, by increasing the rpm points below the area you peak to 100%

8psi is all i get...(wastegate boost) This shits confusing i hate it!!!

I am using the EBC function in "open loop" mode. There are intructions for this that you can follow in the installation manual.

When in "open loop" mode (to enable this set the "closed loop" Kpa limit to 0) it will just follow the instructions you set in the "boost duty target" screen. This makes it ignore anything entered in the Boost Kpa Target Table (apparently closed loop EBC is fancier and all a bit experimental...).

Anyway, in "open loop" mode, the EBC takes the boost levels your wastegate gives you and then adds to it where you want it to in the rev range. So if you see on your first baseline, wastegate only datalog that you are getting 10psi at 3K revs dropping to 6psi at
6K revs, you add duty cycle (time the solednoid is operating) at the points in the rev range you want to get the boost you want.

The defualt settings for the PNP in "open loop" is 20% in each column. On your first run with the EBC operational you should see that your boost curve has changed. At this point you can slowly raise the numbers in the fields to get the boost level and curve you want (go slowly you don't want to hit 30psi accidently). If it goes too high, then you do the opposite and reduce the number in the appropriate column.

Doing this is actually easier (and quicker) than having to sit down and write out how to do it. Is there anyone else near to you that can pysically help?

Good info there...

I just spent some time earlier today documenting this a bit better than what we previously had and adding it to the MSPNP manuals online. Check it out in the tuning section of the manuals at www.megasquirtpnp.com

I'll be going back soon and adding pics showing the physical installation stuff using our valve (hose routing and whatnot).

This link will take you to the top of the tuning section of the MM9093 manual, you'll have to scroll down a bit for the EBC tuning section:

I need some help. ECU is DIY PNP MSII Built by Brain

I have been struggling like hell for weeks now trying to get my EBC working.
I have boost settings set so boost control is enabled. What should open and closed duty % be set at 100 and 0 and if so which way round. Is it supposed to be open 100 and closed 0.

Then as was said I changed the values on the boost table to 20 and ran down the road hitting overboost protection at about 22psi or so. I have overboost set to 250kpa as from the guide in the link above as im aiming for around 20psi.

It would apppear that the EBC isnt functioning at all.

Scott I know you have told me a while ago but ive lost the thread or PM you sent. What do I need to alter on tunerstudio to get EBC to work?

Am I mising something really obvious?
