MaTTSuN Posted August 28, 2007 Share Posted August 28, 2007 ok now i got everything working took her out for a datalog party drive haha first one was about 10 min in downtown vancouver where i live the msq was not very good and it was very rough so i changed it back to the first setting but then i went for a highway drive for about 30 or 40 min with some city mixed in on the way back home got megalog viewer to analyze and wow what a different car smooth smooth smooth i am very excited to keep tuning this megasquirt thing is turning into everything i dreamed it would be the only problem is i have a vac leak so when i start to build boost it just pops and snaps and i can smell raw fuel i know what the problem is and ill fix it tomorrow after work i cleaned my injectors and one of the seals that holds the injectors in was messed because the housing was missing a big peace either that or one of those little rubber grommets onthe end of the injectors is missing either way i know i got to take the injectors off tomorrow because i broke a injector cap when i was cleaning them and i have some more at my dads i should have some housing also for the injector that has a broken one. so i hope i can make some boost data log runs and get this thing really moving its not half bad now just in vac cant wait to really feel the boost bwahahaha Quote Link to comment Share on other sites More sharing options...
supraspaz Posted August 28, 2007 Share Posted August 28, 2007 That is really quite encouraging to hear. I cant wait for my motor to be back from the machinist so the fun part can begin. what setup do you have and can i borrow your msq just to have a peek. It would be nice to get an idea of what a decently tuned setup looks like in megatune. Quote Link to comment Share on other sites More sharing options...
datman Posted August 28, 2007 Share Posted August 28, 2007 Great job! I'm at the same point as you...megalogging drives...only at 10psi so far but it is so fast its scary....4th gear from 40 to 100 is like a rocket. What spec have you got?

naviathan Posted August 28, 2007 Share Posted August 28, 2007 Awesome. I can't wait to get my car back together. I think most of my problems were due to the lobes wearing and wiping out. I was trying to use MAP Dot accel and it was all over the place. Makes sense, uneven vacuum pull from cylinder to cylinder would make it crazy.

MaTTSuN Posted August 29, 2007 Author Share Posted August 29, 2007 im running the V3 board fuel and spark i just got the boost working today i had an injector seal missing so i put that badboy in and off i went it pulls pretty well i guess im still spoiled form my 929rr for speed but thats off the road and im getting used to this car thing i did a run up one of our local mountains and was following a bike around a nice big bend then he took off up the hill it pulls fairly well but it seams like it kind of hits a wall at 4000rpm either that or i am just to scared to push it past but it seams like it does hit a kind of power wall at 4k ill post a msq tomorrow when i get some more time with boost the one i have now is like an hour in vac what should my VE map be set for max kpa? im only making 8 psi not sure what that is in kpa i got the conversion somewhere should i set the map up for max 10 psi?

datman Posted August 29, 2007 Share Posted August 29, 2007 No expert but I set my ve map up to 220kpa ...100kpa is atmospheric sea level so 200 would be 1 bar or 14.7psi of boost. So I guess thats about 17.6 psi max on the chart, I think it will use the last enty as a value if you go over that. http://forums.hybridz.org/showthread.php?t=99689 check out post #32 Dave has his Map and Rpm values set up well.

cygnusx1 Posted August 29, 2007 Share Posted August 29, 2007 Power comes from the timing maps. Once your AFR's are all in the 12:1-14:1 range all over the place with 12:1's in the high boost areas, you can begin the timing tuning. Go easy on it. Little by little. I idle at about 25btdc and I am at full advance (40btdc) by 3000rpms all the way to redline. Reduce advance by 1.5 or 2 degrees per PSI in the boosted areas. BE CAREFUL. You can blow a hole in the head gasket or a piston. Luckily, I only blew the gasket. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted September 3, 2007 Author Share Posted September 3, 2007 ok ive been driving the car for about a week and now i want to get some more power out of it at 8psi ive changed my ve and spark table to max out at 170kpa about 10psi i still have to go for a drive at these settings but i filled in the gaps from my 250kpa settings... i reworked the spark settings . 2 deg drop for every psi of boost give or take. is less drop or more drop safer? do u want more timing in boost or less? i have it set at 40 at 3000rpm and under 100kpa and dropping 2 psi at 110 4 at 120 and so on is that safe to run?

cygnusx1 Posted September 4, 2007 Share Posted September 4, 2007 You want less advance at boost. If you have 40deg advance max at no boost, you want between 20 and 25deg at 10psi. Just an example. Quote Link to comment Share on other sites More sharing options...

Reduce advance by 1.5 or 2 degrees per PSI in the boosted areas. Why is your idle timing so high? Shouldn't it be close to what the stock setting is, mine is between 12 and 15 I think, stock is 8 or so. Quote Link to comment Share on other sites More sharing options...
ktm Posted September 6, 2007 Share Posted September 6, 2007 Idle for a stock turbo motor is 20 to 24 btdc. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted September 10, 2007 Author Share Posted September 10, 2007 i have my timing at 40 about 3000rpm ive got my idle timing at 24 i think i just went threw my vacume to make my car more driveable and its running smooth as silk in vacume running good in boost also cant wait to turn it up its set at 8psi right now after i get my oil cooler on ill start putting more boost in and thinking about an intercooler but 12 psi should be ok without one..
