Ok all you Turbo people -
I can chip ECU's for up to 16PSI of boost. I've been working pretty much all spring on this project, I have several people testing my chips with great success.
I'm making a page on my website about them, but its not up yet. In the meantime heres the important details:
-Raises Boost Limit to 16PSI
-Richens Fuel Map
-Increased/ Custom Rev Limits
I am charging $150 for this upgrade. That includes socketing the ECU, programming and installing an aftermarket EEPROM chip, and shipping back to you.
If you want I will also return the stock chip with the ECU so if you want to revert to stock, simply take the cover off the ECU, unplug the RocketChip and plug in the stock chip.
Turnaround time is about as fast as Priority mail moves.
I can also modify N/A chips but to what extent I dont know. I dont have an N/A car to test it on.
I'll be away on holiday next week, so I'll start taking orders when I get back.

Do you have a 16 psi dyno with the plot for your AFR plotted, that would be awesome. Is there any way that you can provide an ECU instead of my car having to go out of commision while it gets mailed to you and back? Did you copy someone else's mapping or did you ake it yourself?
Thanks

I dont have a dyno run yet - its in my schedule (*somewhere*. heh). I am running a Wideband O2 sensor right now, and in the lower rpm's it in the low 13's mid 12's and high RPM its near low 12's.
Yes I have a spare ecu I am willing to use for an exchange service.
I didnt copy anyone elses work. I've looked at other chips to see what they have done, but I have not copied anything. After testing the other chips I found a few issues with them that I didnt have in my own chip.
Like I said I'm working on a site that will have the fuel maps laid out in graph format so you can see whats been changed there.

That's way bad-ass I'll probably be in touch after I finish a few other mods.
-
I'd like to ride in one that has this mod. If I get my XR2 running correctly Iwould definitly be interested!!!!
-
I'll be at the MACG, and i have no problem showing people what this chip does (http://smile.gif)

These cars SCREAM at 16PSI. Easily puts you back in your seat, especially if you have supporting mods to accompany it. (good intake, free-flowing exhaust, good spark plugs, ect)
I will be bringing my equipment to the MACG so I can chip ECU's there. We'll try to work out a deal for anyone that buys one there.
-
Is that the meet in Rockford? If so, I'll be there if my car is still road worthy. I'm looking for a demo drive/ ride. (http://smile.gif) Will it boost the stock turbo to 16 psi, and do I need to adjust something so the turbo spins that fast?
-
The chip only alters the engine management to safely run more boost. You have to remove the boost cut switch (or just disconnect it) and you need a boost controller to allow the turbo to boost higher.
There are electronic and manual boost controllers. The manual ones are cheap and effective enough. I have one in my XR2. They intercept and alter the boost line to the wastegate and fool it into opening later and at a higher PSI.
-
By the way... this is true in my car... just to put this into perspective... my Capri is faster than my buddies 1989 Mustang GT 5.0
All I've done is add the RocketChip, manual boots controller, new Blow Off Valve, and new spark plugs that are 1 or 2 degrees cooler than stock. I also have the strut bar, but that doesn't really effect acceleration much. The chip is well worth the investment.

Are you still using the stock injectors and pump? How does it react under less than WOT conditions?
-
Yes still using stock injectors and fuel pump. Really dont need much more untill you get over the 200hp mark.
Off boost, and under partial throttle, its like normal. Its usually much peppier, becuase of the boost controller.
Gas mileage is the same as long as you keep out of the throttle, I got 35mpg highway the last long trip I took.

I just sent you the PayPal. I can hardly wait...
By the way, what were the references to MACG and Rockford? I haven't been on lately, so I didn't hear about it.

The capri meet will be start at a dragstrip in Byron I think? The it moves to Freeport.
I got your payment, I will send out your ECU ASAP.
-
You da man. Ignore my PM.
-
Send me a tracking number once it ships. I want to keep an eye out for the package.
-
Sorry I was away when you posted that and I didnt see it.
-
Not a problem. I sent you some e-mail. The 3rd one is from today. Is the ECU a 323 GT/GTX or an XR2? I'm getting a code 27 when I check DTC with the chipped ECU.
-
Wheee... back from the dead. I'm sort of curoius about what sort of airflow you can see with your chip before it goes lean and starts blowing up. I know you've done the VJ-11 swap a couple times, are you getting good fueling at 16 pound with that? I want a vj-11 but don't want to blow up. The set-up would be full vj-11, intake, 2.5 dp and exhaust, no cat, 2 inch intercooler piping and a healthy sized front-mount, what do you think?
Oh, BTW: I've been saving for 2 months to buy a chip and am about half way there so I'm buying one whether it'll fuel a vj-11 or not.
-
I am not running a VJ11 on my current capri but the Rocketchip will support a full VJ11 without leaning out.
You have an AIM screename listed...are you ever on? Hop on some time and msg me.
-
I'm only on AIM when I'm at my dad's house and on mondays from 3:30-4:30, I'll be at my dad's from 12/26 until 12/30 so I'll try to catch you then, if that doesn't work for you just pm me or e-mail me.
-
Got the ECU! Thanks! Let me know when you receive the Deluxe Boost Controller.
-
and let US know how the thing works for ya (http://smile.gif) I know i enjoy mine
-
Yea, sadly, it's going to be 3-4 weeks probably by the time it's all put back together to get this thing running again but, lets hope for sooner. Can we all do a Build Faster Dance ritual so I can get my baby back on the road/track?
-
im intrested any HP numbers??? my cars got about 102k on the clock any chance of me blowing it apart with this chip @16psi? im a newby to the capri world help a guy out with questions (http://smile.gif)
-
You can expect 15-30 hp depending on what other mods you have done. You'll be fine as long as you keep the boost at 16psi.
-
Rocketman,
I sent an email a week or two ago to your werbakfik email address but didn't get a response. Are you still supplying the rockchip? What is the best email address to contact you?
dennis
-
Dennis,
I have not been on top of checking that email address, I apologize.
Best way to get in touch with me right now is to send me a PM here on TeamCapri.
-Rocketman
-
Rocketman,
I tried emailing you at werbatfik and tried a personal message here with no response. Is there another email address I can us. I have some questions about ordering the ECU rocketchip.
dennis

I replied to your PM.

Rocketman-
I was surfing eBay last night looking for a boost controller, when I came across the A'PEXi USA Digital AVC-R Boost Controller. Opinion?? Do you know anything about this unit? Reason I ask, is I was going to get a manual controller so I can use your RocketChip in my 92. While surfing eBay, I saw a picture for the APEXi unit, and realized I already have one!! It came installed in the ClubSprint, and I had no idea what it was! I know you can do a lot of things with it, but for the $300-500 they get for one of these, it better drive the car as well!!!
So, basicaly, my question is, what's your opinion of these units?
Thanks!
---Russ

I have no personal experience with the unit. However have a read over at SCC, they reviewed the unit in question: http://www.sportcompactcarweb.com/tech/0207scc_a_pexi_avc_r_boost_controler/index.html (http://www.sportcompactcarweb.com/tech/0207scc_a_pexi_avc_r_boost_controler/index.html)
I can help you figure out the wiring install, it really taps deep into the harness to get all of its info. Maybe just copy it from the clubsprint?
And as they noted there, things seemed to have got hairy after a little while. I've heard plenty about that on high-end electronic boost controllers, they use what is called "fuzzy logic" to try to learn boost curves and tailor toward your engine/turbo. While sometimes this works great it can be real trouble to try to get it to learn some turbo systems.
If you've got it great, I would say give it a shot if you can. If it doesnt work very good i'd say toss it on eBay and pick up a nice MBC.
-
Well, I think I've decided to go with a MBC, over the A'PEXi unit. I really don't want anything to complicated, and I don't have time to mess with a unit that complex. Besides, I can put it up on eBay, and put the money towards a much-needed paint job!!
Thanks for the input!!

ROCKETTMAN I MAILED YOUR ECU THIS MORNING,3-5 DAYS. HOW ABOUT THAT J-PIPE YOU HAVE LAYIN AROUND,WHAT DO YOU WANT FOR IT?
ROCKY
-
rocket man with the rocket chip do you have to run 16 psi is that what the map is for or can you tune down the boost to say around 11 -12 if you want due to the b e a utiful mass weather
-
You can tune your boost controller to run anywhere from stock boost all the way up to 16PSi. some people prefer to only run 12 or 14 pounds of boost it's really just how much power you want from your engine.
Personally I have a dual stage controller, that at the flick of a switch I can go from 12psi to 16psi. I also have a pretty aggressive turbo so that small difference in boost is a huge difference in power.
-
what is the turn around on these?
-
I will usually have your ECU modified and sent back out within a week.
-
once i get my car emmission tested i will get with you
-
is this something I could mod myself so I don't have the down time of shipping? I am very good with electronics and have had a lot of experience with auto electrical. just seeing if you would ship the parts for me to do this or if you are not ok with doing that.
-
if you are a master at soldering on a VERY tiny scale... then you could just buy the chip and solder it in... but if you cross any of the contacts... you could fry your ecu. I suggest doing what I did, and do the core deposit... RocketMan sent me a chipped ecu, and when I got it installed, I sent my old one to him. (I believe RM still does the core deposit program)
-
Unless you have no skills whatsoever damaging the board is the least of ones worries. The board could be socketed and the chip installed. This would eliminate the possibility of overheating the chip, the most likely part to be damaged.
-
well I do lots of soldering for my job making MIL eliminators I am always working on parts that are small. I'm not worried about my abilities with something like that at all.
-
this sounds amazing! i am really interested however i want to make sure that 16 psi is safe for this motor right? i would rather have less power and keep it on the road for a while bc i love my capri!
so if you ensure me that it is safe i could prolly order one in like 2 weeks from you... send me a msg with what you think
