umm i was just wondering...if anybody had a map for the Megasquirt from DIY that is set for a halfbridge setup...i just need to get the car to start....tomorrow and I was just wondering if anybody had it. Let me know asap. thanks again...

PS im new to tuning and such....would any map work from any standalone as a guide...or does it have to be MS specific?

Saheed

 

I will give you my map.


Share CAR specifics and I will tell you what to change. If using standard primary injectors then boost Req_Fuel from 7ms to maybe 9-10 and that should get you started.

 

Here is my map for a 12A street port with twin 50mm IDA throttle bodies, race style header collecting at gearbox. S5 Turbo 550cc Primaries, and 870cc secondaries.

Fan Relay output on IAC1A

Code Version is ms2extra1.0.2

 

Halfbridge setup with 820 primaries...(i have 550's available) and 1600 secondaries

Thanks Jobro for your information. really appreciate it.

 

Most street port maps will be way too lean.

Just generate a VE table with the engine constants dialog and the car should start on the default settings. Bridgeports require a LOT of fuel.

 

ok thanks aaron

 

I already told him to further enrich my map 30%, and it was only meant to get the car started.

 

I have just about the same parameters to work with. Bridgeport, 820cc primary, 1600c secondaries, etc. I am looking to just start my car aswell. If you adjust the MSQ file, let me know if you can share it.

 

will do ill let you know in a week

 

That would be awesome if you could do that. I am not a "tuner," I don't have enough knowledge/experiance with a full standalone to start messing with engine parameters.

 

best start learning, but its not as hard as you may think! By feel I could get the engine AFR's inside the 12:1 to 17:1 region and I'm a total novice. WB02 is needed to get it spot on tho.

 

alrighty.....soo we got the car started and idling at 1.5k....but since we didnt have no exhaust...and it was 4am in the morning...we got a noise complaint. For the person that wanted the map...ill post it later today. just woke up from 2 hours of sleep. feeling great...cant wait to go back to her but first got to drop her off at exhaust shop....

 

Awesome! You should post some videos of it as well!

 

I will in just a sec....i have to wait for a friend to come back

 

Hey i was wondering...usually what kind of timing does a halfbridge usually see. I have it currently set at 17 degrees advanced and its very rough during idle.... I figured maybe i can drop down to 12 maybe even 10 degrees advance...i just need some input from those who have a nice soft smooth idle. thanks

 

I run about 12 degrees at idle, 30 degrees at low RPM low load, tapering down to around 20 degrees at atmospheric (with a few more degrees added as the RPMs rise), around 15 at low boost, 10 degrees at high boost.

 

The 1st file is what I got his car was running on when I left that day. The 2nd file involves a few changes. The timing map is actually a slightly modified one based off of one that was copied from another forum member on here.....I believe it was a 12A bridge setup.

 

My 12A street port idles very smoothly at 5ATDC (yes, that's after) verified by strobe. I have the map set to move that to ~10BTDC by 1200rpm or so. IMHO, idle timing is not an arbitrary number - each engine/setup/installation may need to be tuned by ear for best results.

 

i figured i'd post this and see if anybody can give me some feed back. Here is my current map on the MS as well as the Datalog with accurate date via Wideband. Thanks.

 

nobody has any input?

 

what kind of timing does a full bridge port usually see?
