Is there any body out there that sales a mega squirt set up that you can plug in and tune.i mean one with the 60 pin male end and a base tune so i can get it to my tuner.i guess i am just trying to get around the wire it my self thing not to good in the wire department .

Yes, its called a chipped stock computer or a stock computer with an Ostrich, otherwise break out the soldering iron and get cracking or hire someone to wire it for you.

So then get an Ostrich and have your tuner tune it or have Rob aka Shelgame do you a new cal if you think its the cal.

What gauges are you using?

no tuners in cali can tune the td logic or smec it sucks.

So do it yourself. There has to be a TM member in Cali that can help you tune it or show your local tuner the video's on what tables to play with. Any decent tuner should be able to figure it out.

You didn't mention what gauges your using? Forged or cast pistons?

You sure its not your ring gap? If not then that is definitely a detonation problem which MS would not fix. Megasquirt does not use a knock sensor, couple that with a novice tuner and you have yourself a really bad setup. I would figure out what is going on first e.g. rings, lean, or just plain a bad cal. I would also go over all your wiring and make sure something else isn't happening like an injector dropping out or a sketchy HEP.

Well, with the WBO2 you know if it's lean, and I have to assume you would let off the throttle if you saw a/f ratios above 12.0:1 (ish). So that leaves the ignition timing. I have seen the timing schedule through a scan tool from many modified computers and they're far more aggressive than stock and probably why you set the base timing at 10, but that's still not enough.

Forged pistons aren't really the fix. They'll still detonate but they'll put up to the punishment a little better before breaking or burning. The correct fix is to find the reason for the detonation (still assuming the a/f are good) Watch the knock sensor output with a scan tool and back out if it gets above 2.5-3v That is pretty much the limit in my findings of detonation.

Other things you can try is colder plugs or non-projected plugs.

If you want someone in Cali, try vprtech (Chris Jensen). He has experience tuning Chrysler electronics and he helped ButchSuppe with his cal.

I would want to monitor knock with that setup for sure. IIRC California only has crappy 91 at the pump. That combined with the very aggressive timing in the stg. 5 cal could take out a motor at 20PSI very easily if you don't watch things carefully.

Most tuners are like personal shoppers. They cater to the gucci end of the crowd because those are the people willing to pay to have them do something they could do themselves.

Turbo-mopars are on the complete opposite end of the spectrum.

I would take the advice here and try to diagnose the problem instead of paying someone a bunch of money to take it off your hands.

Cast pistons won't take abuse like forged as you know, a few have taken cast along way with the proper tune.

If your running Cali's 91 gas, that's half the battle, I would get it running for now, keep the boost low and monitor using a scanner, then go from there. Consider alky injection too.

yeah FWD stage 5 on a 2.5L on 91 pump with 20psi is going to break stuff.

was the cal set up for a 2.5L in the first place? what year car?

its a 1991 dodge shadow es 2.5 board 40 over 5 speed ported head 3inch exhaust side exit +40 inj adjt fpr set at 55 t3/t4 hybrid the cal was made for my car it was set for 91 i was running 110 octane race gas and i had colder plugs the air fuel was at 12 ive got a good sized front mount its a cheepey. it was a pretty hot day at sacramento race way that day like 105

with that much boost id shoot for 11.5:1 afr.

id also start out with stock 2.5L T1 timing tables and go from there.

ive seen way too many cals (from lots of folks) with S60 high octane mode timing plunked right in there.

Yea i asked for them to just keep it stock just make it so i can use a 3bar map and run more boost.

Aries_Turbo
01-12-2011, 10:22 PM
you cant use stock timing values for boost higher than 14psi though and be able to run 91 octane and have it last.

the timing advance needs to reduce as the boost goes higher.

The first stage 5 comp I got had issues it would cut the fuel out from time to time so by the time I got my second comp maybe the damage was already done and it's not the comp at all. For the piece of mind I would like a second opinion so shelgame. If your willing to take a look. At it just tell me where to send it.

Take a look at what? I doubt I could make heads or tails of FWD's cal. I'd just start from scratch with my own.

ShelGame
01-13-2011, 04:19 PM
Sure, but you don't need to send me your computer unless you're just not comfortable swapping chips. I'm sure the FWD computer is socketed. I can just send you a chip. If you want to palce an order, please go to http://www.boostbutton.com/Calibration-Products.html ; select 'LM/SMEC Custom Cal + Chip' and make sure to fill out a spec sheet using the link near the top left of the page...

so her chip can just be plucked out and yours droped in and what about the white rtv tamper seal she puts over the chip that should come right off no harm to the board.

You should be able to peel that off - unless they sealed the chip up completely. That's not usual, though.

your attachment didn't work.


Last week I had the LM fail in my car. I was using an FWD stage 5 computer. I pulled the FWD chip out and tossed it in the trash. I was using the socket to install my own chip but the socket ended up failing. Well at least the solder joints failed anyways. I have a couple socketed LMs so I swapped the LM with my chip and took off to work. I need to fix the joints but I my solder iron is a box in my garage somewhere. I'd guess I am not the only one that got a bad solder job to take a look if you are having issues.

I think there was a bunch of problems. The intercooler had nuts in it from mice, I think it was out of time from the oil pump about it fail, and it was rich from being scaled for 72lbs injectors instead of 81lbs (because of our raised fuel pressure). The fuel pump failed also. Well at least I think it did, with it running e85 now and socket issues I am not sure. The pump wasn't coming on. I hot wired the coil to drain the tank and I had to bang on the tank to get the pump to run. After I changed it the next morning the car wouldn't start. I didn't hear the pump. So with the key on I reach down and wiggled the chip. As I did that the pump cut on and off. Odd to have that problem back to back. Not sure if the hot wire trick requires the LM to be hooked up, if it does I swapped the pump for no reason. Well I needed to upgrade to a 255 anyways with e85.

Not to take this too far off topic, but you don't need the computer hooked up to jump the coil from the battery to energize the pump.

Buckwheat, so you said you "keep" breaking ringlands, has it happend more than once? was it the same piston? was it piston #3?

where did you get the +40 inj from and where they new?

are you running a bath tub or a swirl head??? and where was it ported? what size valves?
