Blitz ECU??????

[CadetLD]

Okay long story short, when i bought my car it came with 2 ECUs one for regular fuel and one for 100 octane. The one for regualr was shot when i got it so ive been running it on the 100 octane chip since day one. Just runs rich and runs like *** when its cold. So I may be doing some dyno tuning soon hopefully and was curious what you guys have to say about this ECU, is it anything special or is jsut a romtuned stock ecu or what? i have no idea what im lookin at besides a sticker that says "access blitz super computer somehting..." anywho heres a pic of it. any info on this is greatly apreciated.

btw ever since i got the car its been giving me the first 5 error codes in my gauge cluster...... Thanks!!! -Shane

I have a Blitz Access ECU in my car too. Doesn't change a whole lot (fuel, boost, rev limit) but for people like me who are to stupid nor have the skills to do one of those fancy standalone systems this works. My car doesn't have much on it either to require another system so this seemed to be the right choice for me. Yours is also missing the Blitz seal, that is what the circular mark is on top of the ecu. There should have been a sticker on there saying sealed by Blitz or something. Someone might have opened that one or may have just fell off. Mine is still stuck on there pretty good.

it's something like a boost up chip tune. i had one for awhile and mine ran really rich also, which is unusual (maybe?) because of the low octane rating of fuels here. usually they're set up for some range of features, more than likely stock everything (injectors, maf, turbo, intercooler, etc) except a free flow exhaust and intake, and maybe a few more pounds of boost, just don't get carried away and turn the boost way up...

I have one too, my car isnt done yet so i havent tried it yet. Mine is also sealed with those stickers. Is there any way to tune them?

[CadetLD]

Well I have FMIC, S15 turbo, stock injectors, strait 3" exhaust, and Blitz filter, right now my boost gauge tells me im only running 6psi of boost at peak. I was aiming for 12-14psi and hopefuly 250ish whp. Can this computer be set up to run with my specs?? Thanks again fellas. -Shane

which maf are you using? i wouldn't do anything if i wasn't sure of my tuning, i would also check to see if maybe it wasn't throwing any codes (for the rich burn). there is a possibility that maybe you could get in touch with blitz and ask them to reburn the ecu to your specs, but i have feeling that would be expensive. see, the problem with these chips is, they're set up to run the cars that came with ca's or whatever engines from the factory and usually when you install an engine you leave stuff that the factory put in out. that, and there are different levels of tune for each chip. so, without actually knowing what that chip is "optimized" for you're taking a risk boosting up...and just as a side, i don't think i'd run stock injectors to 12~14psi on a t28. i had a s13 sr turbo at 14 psi and the factory injectors weren't up to the task. just my opinion...

When you say "100 octane" are you talking about the R+M/2 method or just RON? Because afaik, north america is about the only place that uses R+M/2 and most of the world just uses RON. And 100 RON is almost equivalent to 93 here.

thats what i understand too. i dont think anyone else really gets that much higher octane gas at the pump than us.

do all these tuning companies start with the "99" ecu? it seems most of the ones i have seen tuned by blitz, mines, etc. have been a "99" ecu. arent those the automatic ecu? i guess it would make it easy for no speed cut and rev limit cut.

Please read this people!!! The rest of the world isn't getting uber octane fuel and we get crap. While 93 octane isn't available locally (91 is the best here) many places in the US can get 93 octane and would be pretty close to the claimed 100 octane that you see talked about in the rest of the world.

If you want more info on RON vs MON, start another thread and I'll discuss it further.

Fist guys the 99 means NOTHING!!!!!!!its the number next to the nissan sigh below the 99 that tells u what ecu it is..Next the PC-23710T is the tune number...that tells u what the ECU is tuned forA PC-23710t ...is boost up/better fuel map/FMIC/Exaust/up to 444cc/and some times z32 mass!!hope that help clear things up

[Masterdebater]

my ecu is computech and the number is "98"...dunno what that means lol

you say up to a 444 inj, how does that work? aren't injector maps pretty sensitive? i'm just curious, because i have access to an "access" ecu , and that is some damn good info, seeing as i never could get my other car to run well on that ecu before. more info please!

mine is done by swat and the number is still "23710". what does this number mean exactly? sorry, im a little boozed. im knee-deep in subaru.

[CadetLD]

i dont plan on boosting that on stock injectors, but basicaly what im asking can this computer be tuned localy to run with my set up and say stock DSM injectors? or would it be kinda like a base tune and i would have to use a AFR contrller to get it running right? i realy dont know a whole lot about the electronics side of these engines so if theres any recomendations to what would help me achive my goal, im all ears. thanks once again fellas - Shane

do you have one of those things that keeps you from driving your car if you're to drunk? you know, a bac analyzer? if you don't you should get one and just see how drunk you can drive

as far as that number goes, my blitz ecu also has the 23710-t, but mine's a 98 ecu...hey, driftready we need more clarification...
