Hello fellow and lady gearheads.

$EEHack is a good site for LT1 flashing / tuning information: http://fbodytech.com/eehack-2/

No worries if you "Brick" your PCM flashing it, TunerCats can replace the flash chip that's inside the computer: http://www.tunercat.com/ I can personally vouch for TunerCats flash chip repairs, been there for flash chip repair more times than I want to admit.

Thanks Dave was able to recover and write a full edit by repairing a plug to the evap solenoid that was causing noise on the aldl bus and also turning off the battery charger as well.
Insofar as flashing my first ecu went, id say successful. Still running a little lean at idle.

Trimanalzer is a good tool for tuning the LT1: http://fbodytech.com/trimalyzer/trimalyzer-how-to/

FYI The link is full of google ads, didn't use to be that way.

there's always been some ads. the ads are pretty random, it's just a script i plunked in there that inserts ads. sometimes it's one, sometimes it's many. i figure most people use ad blockers anyway, the ad revenue pays for a chunk of the web hosting

still have not had a report of flashhack bricking an ecu, except that one guy who failed during an erase and then decided to press 'read' instead, an odd choice i didn't really plan for...

Hiya Steveo

I updated my laptop last weekend & reflashed using Flashhack for the first time, & installed EEHack 4.93 from 4.91
The upload worked great, no issues.
On the datalog though it reported the AFRTarget as 0.40 and never changed.
Everything else seems OK. I haven't had a chance to delve any further.

It could be a missing "afr target" patch in the bin file you have flashed.

The bin was edited on the PC with TunerPro, same as usual and then flashed with Flashhack in the car rather than EEHack 4.91.
Where would it have lost the patch?

Thanks
Mitch

I really had no problem using your software and the user friendly interface is what have me the guts to start tuning before I probably should have, but so far so good. I'm barely literate in any computer skills but would like to offer any help I can testing or ?. I'm just scratching the surface of the tuning game and desperate to get a richer tune installed asap, mechanically the car is tip top but the list of parts needed is growing fast.ie pump,injectors,regultr..
Any pointers towards recent articles or info would be awesome, I can't believe how far behind I am, this area of auto moding passed me by completely. Time to catch up

man a turbo build is a rough first tuning project but at least its low boost.

are you going to run a 2 bar map sensor or what and are you somewhat familiar with what that entails? the stock tables and map sensor are only good with vacuum, not boost

i have seen some people keep the stock map sensor with a maf with smaller turbo builds, downside is you pretty much only have one column of timing advance for 'on boost', and if the maf ever fails, you would want to keep it out of boost because speed density wont work

Well yeah now you know me that's me in a nut shell. Never the easy way.
The map sensor and maf have been my last couple nights study and I have no conclusion yet. And I'm not at all familiar with any of this yet. My head is spinning from all the variables and my notes look like gibberish. But if all else fails there's a dynotuner about 50 miles away in vancouver.
Can the map and maf tables be modified to handle boost? Is there a better method?
Sorry for the freshman questions but I'm hungry for info and really need this build to work, right now its to lean to drive in closed loop. But all sensors are working and wideband gauge is almost ready to start logging but need how to hook gauge to laptop. I think its the same as aldl to laptop.
Anyway I'd like to richen the mix or be told its ok to log data at this point. Haven't driven it in a week since gauge started working correctly. Shows full lean unless i blip the throttle.
As for the stock map/maf idea, sounds like my kinda option, foolhardy and slightly dangerous. I was thinking I should double check my maf reads correct as I descreened and port matched it before I knew any better.
