I had the same problem with my PTE 5457rb turbo. the car would close the throttle plate. I set the dal tables up to match how the turbo was spooling (which looks way diff. than the stock dal tables). it was in the 100 % area until about 4k when the turbo really started coming on then I ramped the dals up like the turbo was spooling and BAM no more under/over boost. (did 410whp at 20psi at 6300rpm) It took a lot of time on the dyno but I know why your dyno's were started so late in the rpm range.... anyway good luck and can wait to see the final results!!!

 

omg
<-------waiting for product to purchase.

 

holy **** guys good stuff.. cant wait till you can push this stuff all out with no ecm nanny's

 

ZZP, this is great stuff!

But I have some questions... You upgraded the turbine wheel correct? Is that similar to the BTF Compressor Wheel Upgrade, and what makes it different? Is yours better? Because I'm looking about going that route really soon, so I was just wondering. Thank-you!

 

I guess you have very little knowledge about turbos. BTF = upgraded stock turbo (different compressor wheel). ZZP replaced the small stock k04 with a bigger BW s256 turbo.

Lots of in depth talk and pictures on this comparo...

 

Yeah , Good luck with that . I have the pro version and begged them a few months ago to release some more tables , Then people started telling me just to wait and try not to get BAN for harrasing them because they were about to get sued by all LNF I4 owners signing a petition.

I can only say so much about it but the simple fact is ALOT of people bought the PRO version under the impression we are going to get more tables and they would keep the I4 LNF up-to-date like we were promised. I even tried to convince them to steal Vince at trifecta away with an offer he couldn't refuse but I guess they are just too damned stuck up to look to other programmers and developers to crack/unlock more tables and think the LNF market is a dieing breed with all the new big V8 platforms ..


The SRT-4 Guys have found a way to modify the stock ECU with a Mitsubishi re-flash so HPT isn't really all that important to them. V8's are a dieing breed also I wish they would just get over the v8 obsession. I understand these are some really hard obsticles to overcome and it doesn't happen over night but I like many others payed for a program that was supposed to be constantly updated to a certain point. In actuallity many people could have reached these numbers with custom turbo setups with more tables. Mad props to ZZP.



- Good work ZZP. Taxes 2010 can you say 500 WHP .

 

We took care of the over/under boost issues right away, but there are a few other situations in which the throttle will close.

 

Out of curiosity, if the ECM is shutting down have you considered the Stage 1 sensors might help out with this? Throttle has got to be closing as a result of the ECM either thinking there is way too much air flow with the tune, or the sensors are outright failing to report proper numbers (or a failure) as you reach the 24/25PSI threshold (if I recall the article correctly) of the stock sensors?

Excellent numbers and great work!! Nice to see a couple companies taking the LNF seriously and not simply shrugging it off as a "limited DI platform". I've said it before, the LNF is still in its infancy (as are DI motors in mass production if you really think about it) and need only be put in the right hands to properly explore its potential.

 

What do you guys think the number can be with no interuptions from the ecm.

 

When will the head be ready to sell??? im REALLY interested on that... also the turbo upgrade.... VERY GOOD JOB GUYS! loving the fact that even thu hpt dont want to update the tables, we have crazy ass companies (like ZZP) that will work hard for us!

 

i'm in for the zzp charge piping and intercooler valve springs probably too.

 

I just wanna say that i finished reading all 7 pages and this is AWSOME!!!!
Can't wait to see a price for a total build.
Chears!!!!

 

I tried maxing out the opt torque table Sunday, but it caused odd spark timing issues, so I had it back to stock. After you mentioned that, I revisited it and found that if I bumped the table a little, then the throttle would stay open later. If I went too far, it would run into the timing issue again, but I was able to find a happy medium where the throttle and timing both tank at about 7800RPM. I guess I can live with that. Thanks for the the tip.

 

this is getting nuts....

ZZP kit
Pistons
Head
Springs
god knows what clutch and tire?

back in the game with the SRTs

 

We opened the cutout and made a few more dyno pulls today and surpassed our 500whp goal.

The highest power we made was 507sae/525std at 25.5psi. At this level, we are battling a lot of misfire issues, which I plan to look into pretty soon.

I'll get some dyno charts up tomorrow.

That was the plan. They got a bit of a head-start, but we will be tearing it up next year.

 

You guys need to video the dyno runs, even if there not perfect, so we can here it.

 

wow you guys are always outperforming and backing it up!!! cant wait to see the upgrades and kits available soon, keep it up ZZP!

 

don't worry matt, when you get the kit out, someone will complain about how it looks, lol


n/m it putting down 100whp more than the competition and has the e.t.s to back it up... it looks bad, lol

 

needz pics and vidz of this shiot lol

 

Fortunately, it looks good as well.

We will get some video and pics soon.

 

whats a world motor ?

 

A world motor? I guess I don't know what you are asking.

 

LOL sorry ... it was meant to be a joke

Very impressive guys!
