I was planing on calling them next week to discuss option and take my block to have them look at it. Ideally I prefer to keep it a 2.0 but a core is expensive, so I may end up doing a 2.1 de-stroke on a 4G64.

 

What is stopping you from building you block yourself with the aid of a machine shop? Is it time, or are you not comfortable doing it? I'm guessing that money isn't as big an issue, as 2.1 destroked 4g64 blocks aren't terribly cheap compared to built 2.0's.

 

you HAVE to hit up scott gray at road race engineering! he's really good at tuning the aem ems.

 

Why an aftermarket ECU? Not sure how or why you decided to do an aftermarket ECU, but there's no reason to run one for anything other than a ***** out 800+ whp engine. Aftermarket ECUs have no where near the capability to protect your motor from a bad tune, bad gas, bad fuel pump, etc. Rebuild the motor, reinstall the stock ECU, and hand the car over to a reputable tuner with experience tuning the stock ECU (RRE, razorlab, Harman, Tuning Technologies, etc)

 

I know its not hard and I rebuilt my old 4 CYL M3 motor than ran great. I would rather have a machine shop do up the bottom end and I will do the rest. Right now I just dont want to do the assembly myself on the bottom end and its not much more to have someone else assemble it.

 

Well future plans is to be at about 500 whp on pump and about 700 whp on race gas so you tell me why I decided to go aftermarket ecu. I have never ran a reflashed ecu in any of my cars before and that word has never been in my vocabulary.

 

I'd stick with the stock ECU even with those HP values. The key is to hand the car over to someone who really knows how to tune the stock ECU.

 

Ya but there is horsepower limitations with running Maf also the fact when you run large cams and large turbo your idle will never been as good as a full standalone... I know my goals with the car and they include needing a standalone.. case closed

 

You seem to know alot and be an intelligent person but you started modding and tuning without an AFR reading?

sorry to hear about your loss

 

Mistakes happen when you jump the gun tring to make a little bit more power. Live and learn from the mistakes that we make....

 

Thebluesky, Do you have EMS? How many have you tuned? I'm 99% sure you can't autotune with the front or rear narrowband o2 sensor... none of this makes sense. I don't really agree with people saying get a stock ecu and a reflash. Speed density>all. i picked up 30hp going to my EMS. It's needed if you want to to anything really big. sure you can have a 42r with a COP system on a 2.3l with the stock ecu but that's really going to be a pain in the *** to tune. Anyways, you sound like a tool spending 2000$ on an ECU and having your buddy tune your car without a 150$ wideband....

 

I have an Autronic PNP and I've messed around with a few AEM's. I don't tune for other people, just myself and a few friends. Past that, I don't feel a resume is necessary.
An ems will do pretty much what you tell it to do, period. If it is not getting the correct signal, it will not interpret the data correctly. I never stated you can autotune without a wideband, if that's where you are going. Reading definitely pwns you if that's where you are heading with your question. I did say it won't do it correctly. I suggest re-reading my posts and they will make a lot more sense.

 

You should really learn something before you blow wads of cash on car mods. You're making stupid mistakes and cutting corners by letting your friend tune your engine management. XS Engineering of course tunes high horse power cars. Eric Hsu's R32 literally rapes TA cars. Even blows away the gmg porsche cup cars.

 

No cutting corners on the next motor. I know XS does good work and from what Ive been hearing is that they dont do much with the AEM EMS. The car has already been sitting for over an month while Ive been doing reseach and looking around for the right process and parts so that I do this bulid right.

 

curiosity is, who is to blame? did he warn you he wont be responsible or did he assure you? if he played the "im a wanna-be pro tuner" string with you, i say he should be a good friend and at least assist with $$$ on a replacement motor.
