New Product : R.N.R Autosport 4AGE 20V Silvertop to Blacktop ECU conversion kit

We have new product for this month;for those who have problems with their 4AGE 20v Silvertop ECU (burned,unstable idle,etc),you now can change to a newer 4AGE 20v Blacktop ECU by using this kit without need to send your car for rewiring,it is fast,less hassle and reliable.No need to leave your car for days in workshops.Free yourself from the trouble of the Silvertop ECU (which prone to leaking the caps) and free yourself from the restrictive airflow sensor where you can run a velocity stack.

The kit comes with the PnP harness for the ecu,with PnP harness for the fuel pump relay(for ecu controlled fuel pump) and the connectors for the MAP sensor and Air Temp sensor.(MAP sensor and 20V Blacktop ecu sold separately) .

Please contact R.N.R Autosport at rnrautosport@gmail.com for pricing,we do ship to overseas.

Thanks you.

Corolla SEG AE101 Blacktop 20V Auto + E-manage tuning

A friend introduced me to a toyota seg owner who wants to tune his e-manage.This is my first time dyno tune an auto 20v,it is quite difficult as it need delicate control of the throttle in order to maintain the car in particular gear,hence it is hard to get consistency on every runs.

None the less,the base run made is quite good and it is very hard for me to squeeze the every bit of extra power and torque.I got it after almost 30 runs,but there is a strange torque dip at 3500 up to 4500,i spend another 47 runs just to tuneout the dip but after using all tricks up my sleeve,still couldnt get it to better.I guessing this is something that can only be resolved on the street,as this car is auto transmission,and dyno loading can't simulate some of the load the gearbox experienced on the actual road driving conditions.

The AFR lean out just at that moment,i'm thinking it caused by vvt switching on.Something we couldnt see on dyno,a further street tuning should resolve the issue.However,there is an increase on torque right after 4500 up all the way to redline,is much flatter.Peak HP increase is quite minimal and happens a bit later than previous,but it still climbing up until 7600rpm,almost at the rev cut and shift point for the autobox.

I want to review this back and find ways to improve the torque curve and AFR lean out issue at low rpm,will be fine tuning on the road.But anyway,owner now happy with current performance.

Silvertop to Blacktop Conversion #18

Another Silvertop to Blacktop wiring conversion done on a Toyota LE,again the owner having problems with the ECU and Airflow meter which he keep replacing it,frustrated he send the car to my friend Garage Daz and the conversion done in 2 days.It only takes a day actually if on weekends since on weekends i have limited time.

Hope the owner happy with the new ECU and trouble free performance.No photos on this post,again forgot to bring digicam.

Silvertop to Blacktop (conversion no.17)

Another Silvertop to blacktop conversion,it was out of the blue so i forgot to bring my camera along,it was an SEG AE101 with silvertop engine,having problems with idling and such, a quick check discovered that the ECU is leaking a capacitor. Owner takes this opportunity to remove the airflow meter and convert to blacktop system.Conversion done in 2 days due to my day job constraint (1 day if on public holidays)..

E-manage Plug and Play harness + OTR tuning..

A friend of mine ask me to make a plug and play harness for his Blacktop 4AG.

He supplied the jumper harness and the e-manage main+ignition harness

Finished Plug and play harness...

Plug and play means you dont need to cut the factory wiring,and installation and removal is quick.Plug it in the car and we went for a tune on the road with wideband O2..

Silvertop to Blacktop ECU conversion

Another SVT to BT ecu conversion, this time is a Toyota LE with 20v Silvertop engine......the owner saw this blog and interested to convert his wiring too,he's having a few problems with idling and the Check engine light was on..so...straight to the job..

Soldering process on the 22pin socket inside the car..

Finished wiring and connecting the ECU..ready to roll..

The engine,airflow meter have been romoved but retaining the stock airbox,battery being charged because it was weak after 2 days..

Another view of the engine...Job finished..Owner happy with the performance

And Yeah....Garage Daz and RNR Autosport presents..

CAMPRO 4 throttle 200hp..hahaha,watch out VTEC..

AE101 SEG 4AFE to AE111 20 Valve Blacktop Swap.

Once again,my partner and good old friend of Garage Daz,trusted me to pull this project off. The car is AE101 SEG, Malaysian Domestic Model (MDM) with 4AFE engine. Owner have bought a crate AE111 20v engine,it comes with 6 speed transmission from Toyota Carib.The engine ecu is included but the wiring is in a really bad shape,it have being cut off by the Auto Supply Shop but he did'nt mind that as he bought the engine dirt cheap...so now it's up to me to graft the AE111 blacktop engine wiring with the AE101 SEG.

This is the stock AE101 MDM 4AFE engine wiring.The car now is almost 18years to the wiring is not really in a good shape,all the connectors are cracking and brittle and the insulation tape is falling off.

Here is the AE111 20Valve Blacktop engine wiring,this will be grafted into the AE101 engine wiring,taking all the necessary wires to run the engine.

AE101 wiring is being stripped off its insulation.

Unnecessary wires are cut and removed, leaving only the vital to the engine operation. Since most FWD Corollas have the starting,charging,a/c and ignition key power supplies run together with the ecu wiring,it is important to separate those things and know which one need to be removed,which is to be maintained,and which is to be grafted with the new wiring.On conversion like this,the big problem would be the air conditioning system,as different generation of Corollas having different air conditioning system.

Seen here the AE111 ecu wiring is placed on top of the AE101 wiring. Grafting session will begin. All wires are soldered and shrink wrap as usual.

Nearly finished,wrapping it with corrugated tube and insulation tape.

Finally,the finished wiring,all routing of the wires follows stock location on the AE101 SEG. One more ecu connector to be grafted inside the car to complete this conversion.

The 4AGE 6speed MT ecu, seen here attached to the wiring for trial start up.

Engine bay view.All the mechanicals are done by Garage Daz.These guys are really pro in 20Valve conversion,engine swap like this only 2 days!

Silvertop + Blacktop spaghetti....

Mr 'Panjang' of Garage Daz called me asking me whether i could do him a favor for one of his customer, an owner of a Toyota LE with silvertop engine wants to convert his stock silvertop wiring with a blacktop wiring and ecu, but unfortunately the previous mechanic failed to fuse silvertop and blacktop wiring together.

This is what i receive from my mechanic friend,the previous mechanic trying to combine both wiring together.The silvertop wiring and blacktop wiring are tapped together here and there but unfortunately it failed, now it's a tangled mess...

The blacktop wiring is then removed and the broken silvertop wiring is repaired. Each broken wire are soldered and shrink wrapped. I then re-arranged to follow the stock silvertop wiring routing and convert the wiring to accept the blacktop ecu which is using MAP sensor compared to silvertop Airflow meter.

Here is the finished product.Good as new...now... into the car ..still have one connector need to be done for this silvertop wiring to run blacktop ecu.


Here's the installed wiring with the blacktop (auto) ECU in place. All things running back using stock sensors.

The car ; silvertop engine,silvertop wiring with Blacktop ECU running on MAP sensor..the stock trumpets will be changed to stainless steel custom trumpets soon.Look how much free space available in the engine bay after the stock airbox is being removed.
